rtl-ssa: Use right obstack for temporary allocation
I noticed while working on PR98863 that we were using the main
obstack to allocate temporary uses. That was safe, but represents
a kind of local memory leak.
gcc/
* rtl-ssa/accesses.cc (function_info::make_use_available): Use
m_temp_obstack rather than m_obstack to allocate the temporary use.
