This flag is only needed to prevent the directClosureCall optimization
in walkCall, when called for walkGoDefer. But walkGoDefer don't need
to call walkCall: at this point in the compile, the call expression
isn't a real call anymore.
Instead, we just need to walkExpr on the function expression.

When constructing struct literals, importers need a way to specify
precisely which field to initialize without worrying about visibility
or those fields being blank. (A blank field doesn't actually need to
be initialized, but the expression needs to be evaluated still, and
with the right order-of-operations.)
This CL changes StructKeyExpr's Field field to point directly to the
corresponding types.Field, rather than merely holding a copy of its
Sym and Offset. This is akin to past changes to add
SelectorExpr.Selection.

Adds code to the compiler's "order" phase to rewrite go and defer
statements to always be argument-less. E.g.
defer f(x,y) => x1, y1 := x, y
defer func() { f(x1, y1) }
This transformation is not beneficial on its own, but it helps
simplify runtime defer handling for the new register ABI (when
invoking deferred functions on the panic path, the runtime doesn't
need to manage the complexity of determining which args to pass in
register vs memory).
This feature is currently enabled by default if GOEXPERIMENT=regabi or
GOEXPERIMENT=regabidefer is in effect.
Included in this CL are some workarounds in the runtime to insure that
"go" statement targets in the runtime are argument-less already (since
wrapping them can potentially introduce heap-allocated closures, which
are currently not allowed). The expectation is that these workarounds
will be temporary, and can go away once we either A) change the rules
about heap-allocated closures, or B) implement some other scheme for
handling go statements.

We used to transform directly called closures in a separate pass
before walk, because we couldn't guarantee whether we'd see the
closure call or the closure itself first. As of the last CL, this
ordering is always guaranteed, so we can rewrite calls and the closure
at the same time.

This CL reorders function compilation to ensure that functions are
always compiled before any enclosed function literals. The primary
goal of this is to reduce the risk of race conditions that arise due
to compilation of function literals needing to inspect data from their
closure variables. However, a pleasant side effect is that it allows
skipping the redundant, separate compilation of function literals that
were inlined into their enclosing function.

For function literals that aren't inlined or directly called, we need
to pass their arguments via a closure struct. This also means we need
to rewrite uses of closure variables to access from this closure
struct.
Currently we do this rewrite in a pass before walking begins. This CL
moves the code to SSA construction instead, alongside binding other
input parameters.

Two simplifications:
1. Statements (including ODCLFUNC) don't have types, and the
Func.Nname already has a type. There's no need for a second one.
However, there is a lot of code that expects to be able to call
Func.Type, so leave a forwarding method, like with Sym and Linksym.
2. Inline and remove ir.NewFuncNameAt. It doesn't really save any
code, and it's only used a handful of places.

These three expression nodes all represent the same syntax, and so
they're represented the same within types2. And also they're not
handled that meaningfully differently throughout the rest of the
compiler to merit unique representations.
Method expressions are somewhat unique today that they're very
frequently turned into plain function names. But eventually that can
be handled by a post-typecheck desugaring phase that reduces the
number of redundant AST forms.
