We had multiple implementations of this logic and with the introduction
of IntersectionType some where not updated. Instead, this is now added
as a property of `DartType`.

Instead of trying to make names assembler-friendly, instead just
quote the symbols names in the assembly output and use user visible
names for function and object symbols.
More specifically:
* This CL changes the symbol name from an assembler-safe version of the
scrubbed name to an assembler-unsafe version of the user visible name
that is then quoted when used in assembly output.
* For code symbols, regular stubs are prefixed with `stub`, allocation
stubs are prefixed with `new` and type testing stubs are prefixed with
`assert type is` (e.g., `stub Await`, `new RegExp`,
`assert type is List<Int>`). Function symbols have no prefix.
* Readonly data symbols begin with the type of the readonly data. If
there's any additional information (e.g., the function name for
objects like `PcDescriptors` when `SNAPSHOT_BACKTRACE` is defined),
that follows the type in parentheses.
* For direct-to-ELF snapshots, we allow symbols to have duplicate names.
Thus, internally we create unique ids for all created symbols and
refactor the ELF and DWARF subsystems to pass and store these ids
instead of the symbol names.
* For assembly output, symbols must have unique names. The namer now
has a `CStringIntMap` that keeps counts of the number of times a
given symbol name has been generated for assembly output. If the
symbol name is in the `CStringIntMap`, then the new count in the map
is added as a suffix to ensure uniqueness.
For example, the first symbol created using the name `_StringBase.[]`
has no suffix. If a second symbol is created using the same name,
the second symbol is instead named `_StringBase.[] (#2)`.
This also happens for read-only objects with additional information if
that additional information is not sufficient to make it unique, and
is added separately from that additional information.
* A further restriction for assembly output is that symbols that begin
with 'L' have special meaning to the assembler. Thus, we keep the
old system of prepending such symbol names with an underscore to
avoid this behavior.
