arm: Fix parsecpu.awk for aliases [PR113030]

So the problem here is the 2 functions check_cpu and check_arch use
the wrong variable to check if an alias is valid for that cpu/arch.
check_cpu uses cpu_optaliases instead of cpu_opt_alias. cpu_optaliases
is an array of index'ed by the cpuname that contains all of the valid aliases
for that cpu but cpu_opt_alias is an double index array which is index'ed
by cpuname and the alias which provides what is the alias for that option.
Similar thing happens for check_arch and arch_optaliases vs arch_optaliases.

Tested by running:
```
awk -f config/arm/parsecpu.awk -v cmd="chkarch armv7-a+simd" config/arm/arm-cpus.in
awk -f config/arm/parsecpu.awk -v cmd="chkarch armv7-a+neon" config/arm/arm-cpus.in
awk -f config/arm/parsecpu.awk -v cmd="chkarch armv7-a+neon-vfpv3" config/arm/arm-cpus.in
```
And they don't return error back.

gcc/ChangeLog:

	PR target/113030
	* config/arm/parsecpu.awk (check_cpu): Use cpu_opt_alias
	instead of cpu_optaliases.
	(check_arch): Use arch_opt_alias instead of arch_optaliases.
