Fixed bot failure after d20bf5a7

There was a failure on windows bit due to format mismatch on
different(Hex and Decimal) platforms even if meaning of output is same.

For example on X86 linux =>
DW_OP_plus_uconst 0x70, DW_OP_deref, DW_OP_lit4, DW_OP_mul
              ^
on X86 Windows-gnu =>
DW_AT_location (DW_OP_fbreg +112, DW_OP_deref, DW_OP_lit4, DW_OP_mul)

: error: CHECK-SAME: expected string not found in input
; CHECK-SAME: DW_OP_plus_uconst 0x70, DW_OP_deref, DW_OP_lit4, DW_OP_mul
              ^
<stdin>:28:17: note: scanning from here
 DW_AT_location (DW_OP_fbreg +112, DW_OP_deref, DW_OP_lit4, DW_OP_mul)
                ^
<stdin>:28:18: note: possible intended match here
 DW_AT_location (DW_OP_fbreg +112, DW_OP_deref, DW_OP_lit4, DW_OP_mul)

Now the test is limited to x86 using REQUIRED and -mtriple.
