a446101677 x86_64: enable struct field reordering 
The blocker for enabling this feature was my need to debug the emitted
assembly without debug info and having to manually inspect memory to
determine struct contents.  However, we now have debug info!

    (lldb) v -L foo bar
    0x00007fffffffda20: (repro.repro.Foo) foo = {
    0x00007fffffffda24:   .x = 12
    0x00007fffffffda20:   .y = 34
    }
    0x00007fffffffda28: (repro.repro.Bar) bar = {
    0x00007fffffffda28:   .x = 56
    0x00007fffffffda2c:   .y = 78
    }

libunwind: Build C files with -fexceptions. 
See: https://github.com/llvm/llvm-project/pull/121819

This fixes LTO for libunwind, so also re-enable support for that.

Closes #12828.

289e9c3507 resinator: Sync with upstream 
Note: This mostly matches resinator v0.1.0 rather than the latest master version, since the latest master version focuses on adding support for .res -> .obj conversion which is not necessary for the future planned relationship of zig and resinator (resinator will likely be moved out of the compiler and into the build system, a la translate-c).

So, ultimately the changes here consist mostly of bug fixes for obscure edge cases.

std.zip: Add ZIP64 support for local file header extra field 
This PR adds support for handling ZIP64 format in local file headers,
when a zip file contains entries where the compressed or uncompressed
size fields are set to 0xFFFFFFFF, and the extra field contains ZIP64
extended information tag (0x0001)

The code now:

Reads the actual sizes from the ZIP64 extra field data
Validates these sizes against the entry's compressed and uncompressed sizes

Zip file format spec.: https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT

This change allows proper extraction of ZIP files that use ZIP64 format in their
local file headers.

Fixes: #22329

257054a146 Revert "disable flaky incremental compilation tests" 
This reverts commit 133abdeda2994886c3476a3faf53f8a911513b32 but keeps
the tests disabled for the wasm target, which is the only configuration
that seems to fail, even though the error looks like a frontend error.
