9eb7e5182b macho: rework symbol handling to match zld/ELF 
Now, each object file will store a mutable table of symbols that it
defines. Upon symbol resolution between object files, the symbol
will be updated with a globally allocated section ordinal and address
in virtual memory. If the object defines a globally available symbol,
its location only (comprising of the symbol index and object index)
will be stored in the globals map for easy access when relocating, etc.
This approach cleans up the symbol management significantly, and matches
the status quo used in zld/ELF.

Additionally, this makes scoping symbol stabs easier too as they are
now naturally contained within each object file.

794beafb9c Sema: validate extern struct field types earlier 
`validateExternType` does not require the type to be resolved so we can
check it earlier. Only doing it in `resolveTypeFully` lead to worse or
missing compile errors.

Now that #11863 is landed, let's expose it to the zig programs that
build stuff via `build.zig`. "Benchmarks" with [turbonss](https://git.sr.ht/~motiejus/turbonss):

    $ zig build -Dtarget=x86_64-linux-gnu.2.19 -Dcpu=x86_64_v3 -Drelease-small=true

*Debug, uncompressed*

    161K turbonss-getent
    1.2M turbonss-unix2db
    448K libnss_turbo.so.2.0.0

*Debug, compressed*

     78K turbonss-analyze
     86K turbonss-getent
    572K turbonss-unix2db
    190K libnss_turbo.so.2.0.0

*Stripped, for completeness*

379beceffd improve test case from previous commit 
Now it checks that the code is correctly compiled rather than only checking
that it does not crash the compiler.

this must be fixed before we release.

1ec50613bf CI: increase stage3 test coverage 
* Use a debug build of stage3 instead of a debug build of stage2 for
   our self-hosted compiler test coverage.
 * Move coverage from stage1 to stage3 for:
   - building self-hosted without LLVM
   - building self-hosted for 32-bit arm
   - test-compiler-rt
   - test-behavior
   - test-std
   - test-compare-output
   - test-asm-link
   - test-fmt

de62bd0647 macho: Pass sections by pointer when slicing names 
We were accidentally returning a pointer to stack memory, because these
arguments were passed by value. It's just an accident that stage 1 was
passing these by reference, so things were alright until stage 3.

65bc4d915d LLVM: lower optional types as byref=true 
This is a possible workaround for
https://github.com/llvm/llvm-project/issues/56585

On my computer it makes stage3-release go from false positive
compilation errors on the behavior tests to "segmentation fault".
Is this forwards progress or backwards progress? I have no idea.

See #11450

c26d9f6287 Read dynstr starting at rpath offset 
Since we know the offset, we may as well read starting there. Still expects
rpath to fit in 4096 bytes; that might be worth fixing in the future.

Fixes issue #12112

b93a38860d stage2: Change optional non-null field to i8 
This is a workaround for https://github.com/llvm/llvm-project/issues/56585
which causes writes to i1 in memory to be optimized to an incorrect value.
Unfortunately, this does not save users from running into this bug with u1
in their own types.

However, this does seem to be enough to get the behavior tests working.
This resolves #11450 on my machine.
