[PATCH] Fix __builtin_printf/all long double builtins

[Andrew Pinski <pinskia at physics dot uc dot edu>]

This patch fixes up the builtins for the long double math functions
and some other builtins (which can take a long double) to be named as
"function_name$LDBL128".

I could not decide if I should put the functions darwin_patch_builtin
and rs6000_darwin_long_double_builtins should be put into 
config/darwin.c
or somewhere else.

OK? Bootstrapped and tested on powerpc-darwin with no regressions.

There is still a couple of patches to the fortran front-end to fix
large_real_kind_2.F90.

Thanks,
Andrew Pinski
