It'd be good to move this code into the language-independent parts of
the compiler, because it'll be needed even for C mangling of \u escapes
in identifiers.

I also have no objection to moving DOLLARS_IN_IDENTIFIERS into aix.h
if someone wants to generate a patch.  The native assembler on all the
ppc sysv stuff is GNU as, which should be OK with $, and it's probably
better to be consistent between linuxes.
