Pre-processed file that is miscompiled

The patch to cgraphunit.c forcing aliases to be output when cgraph decides so
causes an AIX bootstrap failure.  The patch shifts the output of the aliases in
the assembly file to earlier in the file, before the definition.  AIX assembler
is a single pass assembler and does not allow forward references.
