f9859c102d fix libc++ exceptions for musl targets 
This reverts commit d31be31267523cadd6d59b52633f2d4a9758a3b4.

The problem was happening due to an LLVM bug exposed by having LTO
enabled for libunwind. The simple workaround is to disable LTO for
libunwind. It can be re-enabled in the future when the upstream bug
is fixed.

See #12828

f8a9bc57ce translate-c: lower discards differently 
This makes translate-c lower discards as `_ = @TypeOf(foo);` to avoid
tripping the "pointless discard" error.

Ideally, translate-c would avoid emitting pointless discards, in which
case this commit can be reverted, however, that is a separate
enhancement.

e323cf1264 stage2: change how defers are stored in Zir 
Storing defers this way has the benefits that the defer doesn't get
analyzed multiple times in AstGen, it takes up less space, and it
makes Sema aware of defers allowing for 'unreachable else prong'
error on error sets in generic code.

The disadvantage is that it is a bit more complex and errdefers with
payloads now emit a placeholder instruction (but those are rare).

Sema.zig before:
  Total ZIR bytes:    3.7794370651245117MiB
  Instructions:       238996 (2.051319122314453MiB)

8e631ee3e7 translate-c: Escape non-ASCII characters that appear in macros 
Macro definitions are simply a slice of bytes, which may not be
UTF-8 encoded. If they are not UTF-8 encoded, escape non-printable
and non-ASCII characters as `\xNN`.

99826a2ba8 Sema: fix UAF in zirClosureGet 
Previously if a decl failed its capture scope would be deallocated and
set to undefined which would then lead to invalid dereference in
`zirClosureGet`. To avoid this set the capture scope to a special
failed state and fail the current decl with dependency failure if
the failed state is encountered in `zirClosureGet`.
