A composite literal assignment
x = T{field: v}
may be compiled to
x = T{}
x.field = v
We already do not use this form is RHS uses LHS. If LHS is
address-taken, RHS may uses LHS implicitly, e.g.
v = &x.field
x = T{field: *v}
The lowering above would change the value of RHS (*v).

Historically, Objects in go/types were canonical, meaning each entity
was represented by exactly one variable and could thus be identified by
its address. With object instantiation this is no longer the case: Var
and Func objects must be copied to hold substituted type information,
and there may be more than one Var or Func variable representing the
same source-level entity.
This CL adds Origin methods to *Var and *Func, so users can efficiently
navigate to the corresponding canonical object on the generic type.

CL 395854 made inline pass to not inlining function with shape params,
but pass no shape arguments. This is intended to be the reverse case of
CL 361260.
However, CL 361260 is using wider condition than necessary. Though it
only needs to check against function parameters, it checks whether the
function type has no shape. It does not cause any issue, because
!fn.Type().HasShape() implies !fn.Type().Params().HasShape().
But for the reverse case, it's not true. Function may have shape type,
but has no shape arguments. Thus, we must tighten the condition to
explicitly check against the function parameters only.

Since CL 391014, cmd/compile now requires the -p flag to be set the
build system. This CL changes it to initialize LocalPkg.Path to the
provided path, rather than relying on writing out `"".` into object
files and expecting cmd/link to substitute them.
However, this actually involved a rather long tail of fixes. Many have
already been submitted, but a few notable ones that have to land
simultaneously with changing LocalPkg:
1. When compiling package runtime, there are really two "runtime"
packages: types.LocalPkg (the source package itself) and
ir.Pkgs.Runtime (the compiler's internal representation, for synthetic
references). Previously, these ended up creating separate link
symbols (`"".xxx` and `runtime.xxx`, respectively), but now they both
end up as `runtime.xxx`, which causes lsym collisions (notably
inittask and funcsyms).
2. test/codegen tests need to be updated to expect symbols to be named
`command-line-arguments.xxx` rather than `"".foo`.
3. The issue20014 test case is sensitive to the sort order of field
tracking symbols. In particular, the local package now sorts to its
natural place in the list, rather than to the front.
Thanks to David Chase for helping track down all of the fixes needed
for this CL.

The comment of the BuildList function also states that the build list contains the maximum version of each module. We just need to create a maximum version cache that maps from path to version, in the beginning of the Req function body.

When the local package has an explicit name instead of "",
this is necessary to get past a cgo plugin test that fails
because of a package signature mismatch. There's something
questionable going on in the package hash generation, and
in particular it went wrong here. Updating the sort order
helps.
This CL is a prerequisite for a pending code cleanup,

In the float test in test_fuzz_mutate_crash, don't assume the mutator
will generate a decimal during mutation. The probability it will is
quite high, but it is not guaranteed, which can cause a flake. Since we
are not really testing that the mutator will do this kind of mutation,
just that a mutation happens, just check that the input is not the zero
value like the rest of the targets.

The test doesn't need to be as aggressive, it _should_ still tickle
the right paths with high enough probability. This should
significantly reduce the memory it consumes, which is at a premium
when testing fuzzing things.

These files are all copied as is from the go/build package, to files
with the same name in modindex (with the exception of build_read, which
was copied from go/build/read.go).
This is being done so that the next CL can show exactly the changes that
were made against the go/build versions.
Unfortunately, git doesn't recognize these as copies, which is annoying.
