All ARM instructions require 4-byte alignment.
(Almost) all Thumb instructions require 2-byte alignment.
When emitting instructions into any section, mark the section
appropriately.
Some Thumb instructions are alignment-sensitive modulo 4 bytes,
but themselves require 2-byte alignment; this applies to some
PC- relative forms. However, these cases will invovle implicit
literal pool generation or an explicit .align >=2, both of
which will cause the section to me marked with sufficient
alignment. Thus, we don't handle those cases here. */
