c41f21121c Add a new x86(_64) arch variant "goldmont-without-xsaves"
Its target arch is goldmont, but without xsaves support.
This ensures efficient execution on a broad range of Intel/AMD CPUs used
in Chromebooks, including those lacking xsaves support.
(e.g. Kaby Lake, Gemini Lake, Alder Lake and AMD Zen series)

Bug: 314243939
Test: Build an image with TARGET_ARCH_VARIANT:=goldmont-without-xsaves

bca786d742 [arm64] Build NDK with PAuth and BTI
This change adds a new arch named "armv8-a-branchprot". The new target
is no different from the usual "armv8-a" variant except it has the
compiler flag "-mbranch-protection=standard" set.

With this flag compiler emits Armv8.3-A Pointer Authentication and
Armv8.5-A Branch Target Identification instructions. All of these
instructions are in the hint space; therefore devices which do not
support any of these extensions would execute them as NOPs.

In terms of directory structure there is no change in the output of
build/soong/scripts/build-ndk-prebuilts.sh script.

Test: build NDK prebuilts

a684540945 Add more comments to arch.go
Make sure every exported function or type has a godoc comment.

Also makes minor changes like unexporting functions that are not used
outside the package and fixing minor style warnings.
