Fold the add (ptr, offset) into ptr[offset] only if the offset is small enough. movwi and moviw allow value of 5-bits only (i.e. 32).

Only pad when the section size > 0 and move the code that deals
with globals initializers to a place we know for sure the global
is initialized.

This is still a work in progress but most of the NEON instruction set
is supported.

is concerned).

Fix another register coalescer crash: forgot to check if the instruction being updated has already been coalesced.

Banish global state from ScalarEvolution!  SCEV uniquing is now done by tables attached to the ScalarEvolution pass.
This also throws out the SCEV reference counting scheme, as the the SCEVs now have a lifetime controlled by the
ScalarEvolution pass.

Note that SCEVHandle is now a no-op, and will be remove in a future commit.

predicate does not check if Thumb mode is enabled, and when in ARM mode
there are still some checks for constant-pool use that need to run.

counts for loops with multiple exits, replacing more conservative code
which only handled constants. This is derived from a patch by
Nick Lewycky.

This also fixes llc aborts in ClamAV and others, as
getUMinFromMismatchedTypes takes care of balancing the types before
working with them.
