Subzero: Make -asm-verbose local var offsets local.

When running with -asm-verbose, assembler directives like the following are generated: lv$__123 = 16 These symbols show up in "nm" output of the .o file, and cause inconsistencies in symbol numbering between filetype=asm and filetype=obj, when doing szbuild.py bisection debugging. The fix is to prepend ".L" to the symbol name, so that the assembler treats it as local. E.g.: .L$lv$__123 = 16 BUG= none R=eholk@chromium.org Review URL: https://codereview.chromium.org/2095633002 .
