[PR99829][LRA]: Fixing LRA ICE on arm
LRA removed insn setting equivalence to memory whose output was
reloaded. This resulted in writing an uninitiated value to the memory
which triggered assert in LRA code checking the final generated code.
This patch fixes the problem. Comment in the patch contains more
details about the problem and its solution.
gcc/ChangeLog:
PR target/99829
* lra-constraints.cc (lra_constraints): Prevent removing insn
with reverse equivalence to memory if the memory was reloaded.
