These loop from 0 to AEK_XSCALE, which is currently defined as 0x80000000, and
thus the tests loop over the entire int range, which is unreasonable
and also too slow in debug builds.

Add unittest to {ARM | AArch64}TargetParser,and by the way correct problems as below:
1.Correct a incorrect indexing problem in AArch64TargetParser. The architecture enumeration
is shared across ARM and AArch64 in original implementation.But In the code,I just used the
index which was offset by the ARM, and this would index into the array incorrectly. To make
AArch64 has its own arch enum,or we will do a lot of slowly iterating.
2.Correct a spelling error. The parameter of llvm::AArch64::getArchExtName.
3.Correct a writing mistake, in llvm::ARM::parseArchISA.

The architecture enumeration is shared across ARM and AArch64. However, the
data is not. The code incorrectly would index into the array using the
architecture index which was offset by the ARMv7 architecture enumeration. We
do not have a marker for indicating the architectural family to which the
enumeration belongs so we cannot be clever about offsetting the index (at least
it is not immediately apparent to me). Instead, fall back to the tried-and-true
method of slowly iterating the array (its not a large array, so the impact of
this is not too high).
Because of the incorrect indexing, if we were lucky, we would crash, but usually
we would return an invalid StringRef. We did not have any tests for the AArch64
target parser previously;. Extend the previous tests I had added for ARM to
cover AArch64 for ensuring that we return expected StringRefs.
Take the opportunity to change some iterator types to references.
This work is needed to support parsing `.arch name` directives in the AArch64
target asm parser.

The ARM TargetParser would construct invalid StringRefs. This would cause
asserts to trigger. Add some tests in LLVM to ensure that we dont regress on
this in the future. Although there is a test for this in clang, this ensures
that the changes would get caught in the same repository.
