romcc: avoid use-after-free
Windows bugchecks on this for a while, so we ifndef'd the free() call out. Now some Linuxes (depending on their glibc) also fail on it, so just remove the call altogether at the cost of some leaked memory (couple hundred kilobytes) because tracking down the precise fix is too hard. In case someone wants to fix it, valgrind sees the issues, so revert this change and work on romcc's memory management until valgrind is happy. To get a fix in, provide a good explanation why your change is actually the right way to fix it - for silencing valgrind, this change will do.
