Fangrui Song 5c29ffda90 Revert "[Driver][test] Replace ^//$ with empty string" 
This reverts commit 4817b7729a.

It caused some `^/\n` and had some objection about its readability improvement.

Fangrui Song 4817b7729a [Driver][test] Replace ^//$ with empty string 
The convention does not add //\n. Having all RUN/CHECK lines separated by //\n
makes editor movement difficult (e.g. { } in Vim).

Daniel Kiss f70baaf71f [AArch64] Add -mmark-bti-property flag. 
Writing the .note.gnu.property manually is error prone and hard to
maintain in the assembly files.
The -mmark-bti-property is for the assembler to emit the section with the
GNU_PROPERTY_AARCH64_FEATURE_1_BTI. To be used when C/C++ is compiled
with -mbranch-protection=bti.

This patch refactors the .note.gnu.property handling.
