[patch i386 win32]: Fix local symbols for x64

[Kai Tietz <Kai dot Tietz at onevision dot com>]

Hello,

This patch makes sure, that for x64 non-underscore target the local 
symbols having prefix ".L" to avoid collisions with user symbols. 
Testcases that have shown this issue are c-c++-common/raw-string-1.c and 
c-c++-common/raw-string-2.c . Additional this patch fixes some testcases 
in gcc.dg for x64 target.
