x86 codegen: don't generate location comments

The following source snippet 'module A where x */* y = 42'
when being compiled with '-g' option emits syntactically
invalid comment for GNU as:

    .text
        .align 8
        .loc 1 3 1 /* */* */

Fixed by not emitting comments at all. We already suppress
all asm comments in 'X86/Ppr.hs'.
