Evan Cheng 93b5cdc5ab Make the test less likely to fail with minor changes. 
llvm-svn: 130778

Jakob Stoklund Olesen 0888bcf542 Fix ARM tests to be register allocator independent.

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.

Evan Cheng 2d59ee34f1 Add some missing isel predicates on def : pat patterns to avoid generating VFP vmla / vmls (they cause stalls). Disabling them in isel is properly not a right solution, I'll look into a proper solution next.

Evan Cheng 34c260458a Change ARM scheduling default to list-hybrid if the target supports floating point instructions (and is not using soft float).

Jim Grosbach 71fcb4fedd switch the flag for using NEON for SP floating point to a subtarget 'feature'. 
Re-commit. This time complete with testsuite updates.

David Goodwin 1cc6dd97da Remove neonfp attribute and instead set default based on CPU string. Add -arm-use-neon-fp to override the default.

David Goodwin 742db6a6d4 Make NEON single-precision FP support the default for cortex-a8 (again).
