The current two-level indexing scheme for function type parameters
(depth and index) breaks down in the case of type substitution when
the substituted type is a generic function type, since its internal
type parameter types have been encoded assuming that the function type
had nesting depth zero, but after substitution its nesting depth can
be higher.
Relative indexing schemes such as De Bruijn indices will also not
work, since function type parameter types are constant types, and the
constant infrastructure assumes that the same constant always has the
same representation.
This change introduces a flat indexing scheme where function type
parameters are indexed using a single index which is independent of
the context in which the type parameter type appears. To avoid
collisions in the case of nested generic function types, every function
type has a type parameter offset, which conceptually shifts the
indexing range of its type parameters so it doesn't necessarily start
at zero.
Looking up a function type parameter in its environment thus involves
searching outwards until a function type is found whose type parameter
index range contains the index encoded in the function type parameter
type.

AsmIntrinsifier::OneByteString_getHashCode now uses the CombineHashes
and FinalizeHash Assembler methods introduced in 49f998dc31.
To avoid having to check for 0 again after masking the result of
FinalizeHash to fit the desired bit size, we create a more general
FinalizeHashForSize that also takes the desired bit size of the result.
The intrinsified versions for ARM/ARM64/RISCV are also modified to
remove the special casing for the empty string, and instead just check
the size of the string against the loop counter at the start of the
loop, similarly to X64/IA32. This is less efficient for the empty
string case, but avoids the need to create a version of FinalizeHash
that elides the zero check.

Since Dart 2.0 we can never have FallThroughErrors.
The CFE does not synthesize breaks unterminated cases which never
reach the end of the block. For example:
* Call to something that returns never.
* Nested complete switch which returns from every branch.
In these cases we need to construct a correct control flow in the VM,
even though it is dead code. Because the CFE does not make the outer
switch a labelled statement, we cannot find a jump target in the VM.
Therefore, throw something (just not a FallThroughError). This should
never be hit at runtime, because it's dead code.
When the CFE emits synthetic breaks, we can remove this workaround.
TEST=build SDK and run default suites.

This reimplements dynamic call code generation to add support for type
checking, named parameters (optional and required), and fixes a few
related bugs on the way.
Currently we do not try to be as efficient as possible. The goal with
this patch is to implement it correctly.
Summary of the changes:
- For every dynamic access kind and member name, we generate a new
"forwarder" function. Dynamic gets, sets, and invocations are compiled
to calls to the forwarders with the right access kind (invocation,
get, set) and member name.
For example, if the program has dynamic invocation of a member "f", we
create an "invocation forwarder for f". If it has a dynamic get of a
member "x", we generate "getter forwarder for x".
- Forwarder functions take 4 arguments:
- Receiver of the invocation, get, or set.
- A Dart list for type arguments in the invocation. For gets and sets
the list is empty.
- A Dart list for positional arguments in the invocation. For gets the
list is empty. For sets, the list only has one element.
- A Dart list for named arguments. For gets and sets the list is
empty. The list has alternating elements of type `Symbol` and
`Object?`, for the name and value of the named parameters.
- A forwarder function compares receiver class ID with the potential
targets of the call. When it finds a match, it compares the callee
"shape" with the parameters passed in the call site.
As it compares the shapes it adjusts argument lists:
- Creates default values for missing optional positional and named
arguments
- Reorders the named argument list to match order expected by the
callee
If it can't find a matching class ID and a member with the right name
and shape, it calls `noSuchMethod` on the receiver.
If it finds a matching class ID and a member, it calls the "type
checker" for the member, passing the original receiver and adjusted
argument lists.
- A "type checker" implements argument type checking for a member, and
it's a member of the same class as the member it's checking types
for. This is to allow accessing class-bound type parameters when
generating type checking code.
- Type checking is implemented using `_isSubtype` on arguments in the
lists.
- When type checking is successful a type checker calls the original
member, passing the arguments as expected by the member.
If type checking is unsuccessful it throws a type error.
Most of the changes are for generating Wasm functions that compare
shapes, adjusts argument lists, and checks types.
Changes to members:
- `Translator.dynamics` fields is renamed to
`Translator.dynamicForwarders`
- New field `Translator.dynamicForwarderFunctionType` added for the Wasm
function type of forwarder and type checker functions.
- Two new code gen utilities added:
- `Translator.indexList`: generates code that indexes a Dart list
- `Translator.getListLength`: generates code that gets length of a
Dart list
- New `Reference` extensions added to get type checker function
references of members
- New runtime library `named_parameters` implements two helper functions
for dealing with named argument lists
- The library `dynamic_dispatch` is replaced by `dynamic_forwarders`,
which consists of two classes:
- `DynamicForwarders`: maintains mapping from call kind (get, set,
invocation) and member name to forwarder functions.
- `Forwarder`: a single forwarder, implements code generation for
forwarder functions.
- `CodeGenerator` gets 3 new members:
- `_callForwader` generates call to a forwarder
- `_generateFieldSetterTypeCheckerMethod` generates code for a type
checker of a setter function.
- `_generateProcedureTypeCheckerMethod` generates code for a type
checker of a method.

* Usage of `()` for `parameters`.
* Empty string return type.
* Known type return type.
On the analyzer instance I've measured on (8 folders with analyzer etc
open) this saves:
Before CL: 161851 kb 2158725 _OneByteString dart:core

The field `Var.errorId` was being used for two purposes:
- For checking error messages.
- To distinguish different variables with the same name when merging
variables in `||` and cases.
As a result, a lot of variables to be tagged with error IDs even in
tests that weren't generating any errors, which was confusing.
This change creates a new `Var.identity` field which is used for
merging variables in `||` and cases; it defaults to the variable name
but may be overridden in tests where distinguishing variables of the
same name is important.
