llvm_{10..13}: backport gcc-13 fixes

[trofi]

Without the change llvm build fails on gcc-13 fails as:

Have yet to run a build but this looks good to me; both patches were backported to LLVM 14 in upstream (1, 2) and the Base64.h patch indeed isn't applicable prior to LLVM 11.

@Trofli have you tried building llvm_{5..9} with gcc-13? It seems like the Signals.h patch would be applicable for those.

Yeah, I built all of 5..13. Don't know why older version don't fail. Could it be those are pinned to older gcc versions already?

Ah, my bad; void CleanupOnSignal(uintptr_t Context); was added to Signals.h in LLVM 10: llvm/llvm-project@a1f1699

I haven't yet tested on Darwin (I should have a chance to this weekend) but otherwise this looks good.
