[Committed] Fix gcc.target/aarch64/atomic_cmp_exchange_*.c for supplied -mcpu=/-march=

[Andrew Pinski]

Hi,
  This test fails if you supply a -mcpu= (or -march) option which
enables LSE (or when you default to having LSE turned on).  This fixes
that by supplying -march=armv8.1-a+nolse and skips if you pass a -mcpu
option.

Committed as obvious after testing on aarch64-linux-gnu with
--target_board=unix/\{,-mcpu=thunderx,-mcpu=thunderx2t99,-march=armv8-a,-march=armv8.1-a,-march=armv8.2-a\}.

Thanks,
Andrew Pinski

ChangeLog:
* gcc.target/aarch64/atomic_cmp_exchange_zero_reg_1.c: Pass
-march=armv8-a+nolse, skip if -mcpu= is passed.
* gcc.target/aarch64/atomic_cmp_exchange_zero_strong_1.c: Likewise.
