ipa: Initialize/release global obstack in process_new_functions [PR116068]
Other spots in cgraphunit.cc already call bitmap_obstack_initialize (NULL);
before running a pass list and bitmap_obstack_release (NULL); after that,
while process_new_functions wasn't doing that and with the new r15-130
bitmap_alloc checking that results in ICE.

PR ipa/116068
* cgraphunit.cc (symbol_table::process_new_functions): Call
bitmap_obstack_initialize (NULL); and bitmap_obstack_release (NULL)
around processing the functions.
* gcc.dg/graphite/pr116068.c: New test.
