arm: testsuite: improve test compatibility of asm-hard-reg-... tests
On arm, overriding -march can lead to warnings if the testsuite
options try to pass -mcpu. Avoid these by ensuring the -mcpu is unset
before adding the architecture.
Also, improve the compatibility of asm-hard-reg-error-3.c for
hard-float environment by allowing FP instructions in the
architecture.
gcc/testsuite:
* gcc.dg/asm-hard-reg-4.c: On Arm, unset the CPU before
setting the arch.
* gcc.dg/asm-hard-reg-error-3.c: Similarly. Also add
floating-point instructions to aid hard-float variants.
Match on arm* not just arm.
