x86 codegen: don't generate location comments

Authored by trofi on Oct 27 2015, 6:06 PM.



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

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

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

Let's not have commented-out code, better to just delete it
