[PATCH] Fix a leak in the C front-end

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

This is the first patch in a series of fixing memory leak problems in 
GCC where GCC
does not use GC memory.
I used the testcase in PR 12440 which is about excessive memory usage 
in GCC, these
patches should make GCC use less memory at the same time which causes 
the ICEs.
After this patch there was no leaks with the testcase at -O0.

Bootstrapped and tested on powerpc-apple-darwin7.2.0 with no 
regressions.
Ok for the mainline?

Thanks,
Andrew Pinski


ChangeLog:
