Jakob Stoklund Olesen edfabc9aad Weekly fix of register allocation dependent unit tests.

Andrew Trick 47ff14b091 Convert -enable-sched-cycles and -enable-sched-hazard to -disable
flags. They are still not enable in this revision.

Added TargetInstrInfo::isZeroCost() to fix a fundamental problem with
the scheduler's model of operand latency in the selection DAG.

Generalized unit tests to work with sched-cycles.

Bob Wilson 3dc97324c1 Add a command line option "-arm-strict-align" to disallow unaligned memory
accesses for ARM targets that would otherwise allow it.  Radar 8465431.

Rafael Espindola 29dda21e96 Remove arm_apcscc from the test files. It is the default and doing this
matches what llvm-gcc and clang now produce.

Anton Korobeynikov 25df248382 Fix a gross typo: ARMv6+ may or may not support unaligned memory operations.
Even if they are suported by the core, they can be disabled
(this is just a configuration bit inside some register).

Allow unaligned memops on darwin and conservatively disallow them otherwise.

Evan Cheng 52d4e64711 Change allowsUnalignedMemoryAccesses to take type argument since some targets
support unaligned mem access only for certain types. (Should it be size
instead?)

ARM v7 supports unaligned access for i16 and i32, some v6 variants support it
as well.
