[PATCH] D84923: [ARM] Fix so immediates and pc relative checks

[Simon Wallis via Phabricator via llvm-commits]

simonwallis2 added a comment.

Reinstated the change to pc offset.
This is necessary for ARM-state SO immediates.

Added a test case which tries to place a constant pool after a gap of a specified count of bytes,
or when that is not a valid offset it falls back to inserting the constant pool locally.
This test is invoked several times at significant offsets to demonstrate that the limits are correct.
