the implicit addressing, dereferencing, and field selections involved
in changing the `x` in `x.M()` into an appropriate expression to pass

Unified IR uses static dictionaries for some itabs and function/method
expressions, and they're roughly the right idea. But at the same time,
they're actually somewhat brittle and I need to reorganize some ideas
anyway to get shaped-based stenciling working. So this CL just rips
them out entirely.
Note: the code for emitting runtime dictionaries with *runtime._type
symbols is still present, and continues to demonstrate that basic
runtime dictionary handling is working.

When a generic interface method is used, we use a special
relocation R_USEGENERICIFACEMETHOD to tell the linker the name of
the generic interface method, so it can keep methods with that
name live. The relocation references a symbol whose content is the
name. Currently this is a string symbol, which is content
addessable and may have trailing zero bytes (for better
deduplication). The trailing bytes can cause confusion for the
linker. This symbol doesn't need to be in the final binary and
doesn't need to be deduplicated with other symbol. So we don't use
content addressable symbol but make an (unnamed) symbol
specifically for this.

For interface method values, we nil check the receiver value at the
point of evaluating the method value. Currently this is inserted by
the backend during walk, but in some cases it's useful to emit them
upfront instead.
OITAB is essentially a field selection operation, like ODOT, OIDATA,

OCHECKNIL is a statement that simply evaluates its unary operand, and

NewClosureVar should only be called to capture locally declared
variables in the enclosing function scope. This CL adds a check to
make sure it's used that way, in particular to make sure it's not
called to capture global variables.
This came up because for generic method values, we desugar the method
value into a function literal that captures the receiver value after
evaluating it. However, due to compiler backend limitations, for
package-scope generic method values we spill the receiver value into a
global variable rather than capturing it normally.
To prevent confusing backend issues when misusing NewClosureVar with
global variables, this CL adds an extra check.

As it can't appear in user package paths.
There is a hack for handling "go:buildid" and "type:*" on windows/386.
Previously, windows/386 requires underscore prefix on external symbols,
but that's only applied for SHOSTOBJ/SUNDEFEXT or cgo export symbols.
"go.buildid" is STEXT, "type.*" is STYPE, thus they are not prefixed
with underscore.
In external linking mode, the external linker can't resolve them as
external symbols. But we are lucky that they have "." in their name,
so the external linker see them as Forwarder RVA exports. See:
- https://docs.microsoft.com/en-us/windows/win32/debug/pe-format#export-address-table
- https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=ld/pe-dll.c;h=e7b82ba6ffadf74dc1b9ee71dc13d48336941e51;hb=HEAD#l972)
This CL changes "." to ":" in symbols name, so theses symbols can not be
found by external linker anymore. So a hacky way is adding the
underscore prefix for these 2 symbols. I don't have enough knowledge to
verify whether adding the underscore for all STEXT/STYPE symbols are
fine, even if it could be, that would be done in future CL.
Fixes#37762

In CL 339309 these were probably copied from the respective
godoc comments in package inet.af/netaddr, also see
https://pkg.go.dev/inet.af/netaddr#IPPort.IsValid and
https://pkg.go.dev/inet.af/netaddr#IPPrefix.IsValid
In net/netip the methods are named Addr. Adjust the godoc comments
accordingly.

Some compilers default to having -fstack-protector on, which breaks
when using internal linking because the linker doesn't know how to
find the support functions.

Doing the test at link time lets us distribute one Linux toolchain
that works on both glibc-based and musl-based Linux systems.
The old way built a toolchain that only ran on one or the other.

Arrange for tests that call setMimeInit to fully restore the old values,
by clearing the sync.Once that controls initialization.
Once we've done that, call initMime in initMimeUnixTest because
otherwise the test types loaded there will be cleared by the call to
initMime that previously was not being done.
