Enable LRA for ia64

Browse source 
This was tested by bootstrapping GCC natively on ia64-t2-linux-gnu and
running the testsuite (based on
2361160681):

https://gcc.gnu.org/pipermail/gcc-testresults/2024-June/817268.html

For comparison, the same with just
2361160681:

	* config/ia64/ia64.cc: Enable LRA for ia64.
	* config/ia64/ia64.md: Likewise.
	* config/ia64/predicates.md: Likewise.
