Robert Griesemer 8f19394b62 cmd/compile/internal/types2: refactor untyped conversions
Based on https://golang.org/cl/284256 for go/types.
Brings this code more in line with go/types.

Adjusted various tests to match new error messages which
generally are now better: for assignment errors, instead
of a generic "cannot convert" we now say "cannot use"
followed by a clearer reason as to why not.

Major differences to go/types with respect to the changed
files:

- Some of the new code now returns error codes, but they
  are only used internally for now, and not reported with
  errors.

- go/types does not "convert" untyped nil values to target
  types, but here we do. This is unchanged from how types2
  handled this before this CL.

Robert Griesemer 7a1aa7dfaf [dev.typeparams] test: adjust more test cases to match compiler -G output
With this CL, the first ~500 errorcheck tests pass when running

go run run.go -v -G

in the $GOROOT/test directory (the log output includes a few dozen
tests that are currently skipped).

Russ Cox d82dcadb57 cmd/gc: clean up string index errors
Unify with array/slice errors, which were already good.

Fixes #4232.

Russ Cox a5d7c1f45e errchk: allow multiple patterns
// ERROR "pattern1" "pattern2"

means that there has to be one or more
lines matching pattern1 and then excluding
those, there have to be one or more lines
matching pattern2.  So if you expect two
different error messages from a particular
line, writing two separate patterns checks
that both errors are produced.

Also, errchk now flags lines that produce
more errors than expected.  Before, as long as
at least one error matched the pattern, all the
others were ignored.

Revise tests to expect or silence these
additional errors.
