ab581c5c30 LLVM: override thlcgobj.g_undefined_ok 
Uses the freeze instruction available in LLVM 10.0+. If we don't freeze undef/
poison values before using them in a calculation (even if that calculation is
something like "and 0", which masks the result completely), the result will
still be undef/poison and will keep propagating.

25999ad8ff llvm: support for opaque pointers 
Will be the default starting with LLVM 15, and required with LLVM 16.
Tested with LLVM 14 and '-mllvm -opaque-pointers'. See
https://releases.llvm.org/14.0.0/docs/OpaquePointers.html for more
information.

60c95032fa llvm: removed Xcode 10.0/10.1 as supported versions

fd125b506e LLVM debug info: LLVM 7.0 support 
Also defined some llvm flags in a negative way so they can be removed from
later versions rather than added

edbddec98a llvmdbg: diflags/dispflags fixes 
Fix MainSubprogram flag for older LLVM versions, as it was a plain flag rather
than a subprogram flag there.

Added visibility flags for procdefs (public/private/protected)

Write flags as enum rather than integer to avoid issues with changing values
across different LLVM versions

1f5efe2a95 * support for constrained sitofp/uitofp with (the upcoming) LLVM 10.0 
(fixes most of test/units/math/troundm, although there's still an LLVM
     optimizer/code generation bug that breaks some qword -> double
     conversions)

c477816100 - removed LLVM support for clang < 7.0 and Xcode < 10.0: those versions 
contain various bugs and can't even complete "make all", so there is no
    point in keeping them
