[x86/asm] Make variants work when converting at&t inline asm input to intel asm output

`asm` always has AT&T-style input (`asm inteldialect` has Intel-style asm
input), so EmitGCCInlineAsmStr() always has to pick the same variant since it
cares about the input asm string, not the output asm string.

For PowerPC, that default variant is 1. For other targets, it's 0.

Without this, the included test case errors out with

    error: unknown use of instruction mnemonic without a size suffix
             mov rax, rbx

since it picks the intel branch and then tries to interpret it as AT&T
when selecting intel-style output with `-x86-asm-syntax=intel`.
