[AArch64] Fix SVE/SME vector length printing in cpuid
A semicolon is treated as the start of a comment by some assemblers causing the vector length to be reported incorrectly, so use a newline instead. - Add volatile asm in row_gcc and row_neon64 Bug: b/5631539 Change-Id: I6b0836fcdd9247ef7b9e8ceda01df3150519ecf8 Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5666060 Reviewed-by: Justin Green <greenjustin@google.com>
