Under certain circumstances the same symbol can be used for different implementations of the forwarders.
The forwarders themselves are already emitted with "internal" LLVM linkage, but some particularities in
the mapping from SILLinkage to LLVM linkage caused async function pointers to partial apply forwarders
to be emitted with linkonce_odr instead, which caused the wrong forwarder to be called at runtime, causing
unexpected behavior and crashes.
Ensure that we nativize the path and consider only the filename starting
prefix to account for file suffixes (e.g. `.exe` on Windows). This
ensures that we properly support other platforms.
If we didn't find an extension result, try again disregarding
invertible requirements since `demangleGenericSignature` won't
include them. This is just meant to be a quick low risk fix that we
can cherry-pick, the proper fix here is to delete all this logic and
just return the nominal along with the ABI module name to filter
lookup results.

After further thought, I realize that it makes more sense
to keep the public API in FloatingPointParsing.swift.gyb
(where we can consolidate the repetitive doc comments)
and have this as a purely internal set of service functions.
This reverts commit 7084ab8e6e.
We already had bookkeeping to track which statement in a multi-statement
closure we were looking at, but this was only used for the 'reasonable time'
diagnostic in the case that we hit the expression timer, which was almost
never hit, and is now off by default. The scope, memory, and trial limits
couldn't use this information, so they would always diagnose the entire
target being type checked.
Move it up from ExpressionTimer to ConstraintSystem, so that we get the
right source location there too. Also, factor out some code duplication
in BuilderTransform to ensure we get the same benefit for result builders
applied to function bodies too.
LLVM no longer tail-calls this on x86_64, so we do not need an autorelease pool. Remove it for i386 as well as that is no longer a target for ObjC interop builds.
Because these support functions used to be implemented in C, they could
be present on macOS x86_64, even though Float16 isn't supported
there otherwise. With the new Swift implementation, we can't define
these functions on x86_64 macOS, so remove them from the expected list.
