fe72463f55 [Mach-O] Set mold's version to LC_BUILD_VERSION 
I chose 0x6d6f6c64 as a magic number without coordinating with other
tools or Apple, but it should be fine.

Implement `--(no-)allow-shlib-undefined. 
This also fixes the `note-property` test which was hanging on my
machine. Turns out `$CC` was stuck waiting to read from `stdin`,
and as such I decided to write something into it.

9a3188bcf5 [Mach-O] Compute LC_UUID using the entire code signature section 
We used to compute a file UUID using only the hashes in the code
signature section. So we computes the same UUID even if two files
are differnet only in some field of the code signature section.

b8f6fe1a1a [Mach-O] Do not fill text segment with 0x90 
0x90 is a NOP on x86-64 but doesn't make sense on ARM.

we no longer need this option.

5228fa2d78 Revert "[Mach-O] Add a hack to speed up code verification" 
This reverts commit f3e1f728d3.
I'm not 100% sure why, but now the code signature verification works
way faster than before. Maybe it has improved in macOS 12.4 which was
released last month?

30222dfb3f Revert "simplify opt_demangle setup" 
This reverts commit f6b661a9051f5657ac701ea9c94dd54a85499365.
We want to make it possible to run two or more mold's `main` function
simultaneously in a single process, so we don't want to make `opt_demangle`
a global variable. That's why it was a thread-local variable.

e45bebd1c7 group undefined symbols when reporting them (#508) 
The output now roughly matches the lld report format, with
each symbol followed by a limited list of places that reference it.
Lld can additionally read debuginfo to report the exact location,
but that would require writing an interpreter for .debug_line.

to set it together with ctx.arg.demangle .
