[llvm] cd9142e - DebugInfo: Generalize test/DebugInfo/X86/convert-linked.ll to run with different architectures

[John Brawn via llvm-commits]

This test, and convert-debugloc test from commit efcd3967a6bf6b66e04e40129104d0b65ba453d2,
are now failing on AArch64:

llvm/test/DebugInfo/X86/convert-linked.ll:5:15: error: CHECK-NEXT: expected string not found in input
; CHECK-NEXT: DW_ATE_signed_8
              ^
<stdin>:43:2: note: scanning from here
 DW_AT_name ("signed char")
 ^
<stdin>:44:18: note: possible intended match here
 DW_AT_encoding (DW_ATE_signed_char)
                 ^

I think this is due to AArch64 using GlobalISel at -O0: looking at the llc debug
output, the location information in DBG_VALUE ends up being $noreg  for some reason
so no DW_AT_location is emitted. Changing to -O1 makes the failure go away (though I
don’t know if that's the right way to fix the test).
