user/llvm14: Fix tests on 32-bit machines
* DWARF info patch fixes issue seen on ARMv7 and PPC. * Dyld patch fixes OrcJIT on PPC (also needed for mesa). * MachO fix is being sent upstream and affects all 32-bit CPUs. * PPC test fix is already upstream, backported to 14 branch. Fixes: #846

+
+This isn't the proper fix, but debugging the LLVM formatter is a bit
+above my paygrade at the moment.
+
+The issue shows up in the DWARF X86 test on ppc and armv7:
+
+error: Simplified template DW_AT_name could not be reconstituted:
+ original: f3<char, '\x00', '\x01', '\x06', '\a', '\r', '\x0e', '\x1f', ' ', '!', '\x7f', '\x80'>
+ reconstituted: f3<char, '\x00', '\x00', '\x00', '\a', '\r', '\x00', '\x00', ' ', '!', '\x00', '\x00'>
+
+With this patch, this error does not occur. Debugging shows that the
+llvm::format overload called in the error case is <long long>, so I
+think it is having an issue converting a 64-bit value on platforms
+where char is default-unsigned.
+
+(pmmx does not show this issue, and has signed char.)
