rtl-optimization/98863 - fix PRE/CPROP memory usage check

This fixes overflow of the memory usage estimate in turn failing
to disable itself on WRF with LTO, causing a few GBs worth of
memory peak.

PR rtl-optimization/98863
* gcse.c (gcse_or_cprop_is_too_expensive): Use unsigned
HOST_WIDE_INT for the memory estimate.
