Turn of ipa-ra in builtins test (PR91059)
The gcc.c-torture/execute/builtins/lib directory contains a reimplementation
of many C library string functions, which causes non-trivial register allocation
bugs with LTO and static linked libraries. To fix this long-standing test
issue, turn off ipa-ra which avoids the register corruption across calls. All
builtin torture tests now pass on aarch64-none-elf. Committed as obvious.
