f9f5a765ad ARM writeback vs. stride operands for VST/VLD.
The _fixed variants have a writeback operand, but not a stride operand.
Split the conditional flag to distinguish the cases.

6dc9e2bf74 Reapply commit 143214 with a fix: m_ICmp doesn't match conditions
with the given predicate, it matches any condition and returns the
predicate - d'oh!  Original commit message:
The expression icmp eq (select (icmp eq x, 0), 1, x), 0 folds to false.
Spotted by my super-optimizer in 186.crafty and 450.soplex.  We really
need a proper infrastructure for handling generalizations of this kind
of thing (which occur a lot), however this case is so simple that I decided
to go ahead and implement it directly.

fb0dfbbff7 Fix pr11266.
On x86: (shl V, 1) -> add V,V

Hardware support for vector-shift is sparse and in many cases we scalarize the
result. Additionally, on sandybridge padd is faster than shl.

For example,

On ARM, "mov r3, #-3" is an alias for "mvn r3, #2", so we want to use a
matcher pattern that handles the bitwise negation when mapping to t2MVNi.
