Subject: ARM: align PIC offset pools to 4 bytes
X-Git-Tag: android-x86-4.4-r1~8529^2~518

ARM: align PIC offset pools to 4 bytes

When building Thumb2 code, the end of a function, where the PIC
offsets are placed, need not be aligned.  Although the values
are only accessed with instructions allowing unaligned addresses,
keeping them aligned is preferable.
