[ARM] builtins: Replace abort by assert in clear_cache.
Summary:
__builtion___clear_cache maps to clear_cache function. On Linux,
clear_cache functions makes a syscall and does an abort if syscall fails.
Replace the abort by an assert so that non-debug builds do not abort
if the syscall fails.
Fixes PR34588.
