aarch64: Support multiple variants including up to 3

On some of the Qualcomm's SoC that includes oryon-1 core, the variant
will be different on the cores due to big.little config. Though
the difference between big and little is not significant enough
to have seperate cost/scheduling models for them and the feature set
is the same across all variants.

Also on some SoCs, there are 3 variants of the core, big.middle.little
so this increases the support there for up to 3 cores and 3 variants
in the original parsing loop but it does not change the support for max
of 2 different cores.

After this patch and the patch that adds oryon-1, -mcpu=native works
on the SoCs I am working with.

Bootstrapped and tested on aarch64-linux-gnu with no regressions.

gcc/ChangeLog:

	* config/aarch64/driver-aarch64.cc (host_detect_local_cpu): Support
	3 cores and 3 variants. If there is one core but multiple variant,
	then treat the variant as being all.

gcc/testsuite/ChangeLog:

	* gcc.target/aarch64/cpunative/info_25: New file.
	* gcc.target/aarch64/cpunative/info_26: New file.
	* gcc.target/aarch64/cpunative/native_cpu_25.c: New test.
	* gcc.target/aarch64/cpunative/native_cpu_26.c: New test.
