[PATCH] D147763: [ARM] Align code to 4-byte boundary after .arm directive

[Antonio Abbatangelo via Phabricator via llvm-commits]

Rebased, updated release notes, updated .thumb to align to a 2-byte boundary, and added a test case

To my knowledge (testing with arm-none-eabi), the GNU assembler aligns code after the .arm directive to the next
4-byte boundary when switching from thumb to ARM mode. It does not seem to emit any alignment when switching
from ARM to thumb mode with .thumb.
