4f467f1082 cmd: remove GOEXPERIMENT=nounified knob
This CL removes the GOEXPERIMENT=nounified knob, and any conditional
statements that depend on that knob. Further CLs to remove unreachable
code follow this one.

Updates #57410.

321a220d50 cmd/link: only add dummy XCOFF reference if the symbol exists
On AIX when external linking, for some symbols we need to add
dummy references to prevent the external linker from discarding
them. Currently we add the reference unconditionally. But if the
symbol doesn't exist, the linking fails in a later stage for
generating external relocation of a nonexistent symbol. The
symbols are special symbols that almost always exist, except that
go:buildid may not exist if the linker is invoked without the
-buildid flag. The go command invokes the linker with the flag, so
this can only happen with manual linker invocation. Specifically,
test/run.go does this in some cases.

Fix this by checking the symbol existence before adding the
reference. Re-enable tests on AIX.

Perhaps the linker should always emit a dummy buildid even if the
flag is not set...

Fixes #54814.

b5b2cf519f go/types,types2: exclude tests that need cgo.Incomplete
Since when go/types,types2 do not know about build constraints, and
runtime/cgo.Incomplete is only available on platforms that support cgo.

These tests are also failing on aix with failure from linker, so disable
them on aix to make builder green. The fix for aix is tracked in #54814

Same as CL 421880, but for test directory.

f4198f85d5 [dev.typeparams] cmd/compile: generate wrappers within unified IR
This CL extends unified IR to handle creating wrapper methods. There's
relatively little about this code that's actually specific to unified
IR, but rewriting this logic allows a few benefits:

1. It decouples unified IR from reflectdata.methodWrapper, so the
latter code can evolve freely for -G=3's needs. This will also allow
the new code to evolve to unified IR's wrapper needs, which I
anticipate will operate slightly differently.

2. It provided an opportunity to revisit a lot of the code and
simplify/update it to current style. E.g., in the process, I
discovered #46903, which unified IR now gets correctly. (I have not
yet attempted to fix reflectdata.methodWrapper.)

3. It gives a convenient way for unified IR to ensure all of the
wrapper methods it needs are generated correctly.

For now, the wrapper generation is specific to non-quirks mode.
