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

llvm-svn: 83218

Restore the -post-RA-scheduler flag as an override for the target specification. Remove -mattr for setting PostRAScheduler enable and instead use CPU string.

llvm-svn: 83215

Remove -post-RA-schedule flag and add a TargetSubtarget method to enable post-register-allocation scheduling. By default it is off. For ARM, enable/disable with -mattr=+/-postrasched. Enable by default for cortex-a8.

Initial support for single-precision FP using NEON. Added "neonfp" attribute to enable. Added patterns for some binary FP operations.

Add a Thumb2 instruction flag to that indicates whether the instruction can be transformed to 16-bit variant.

Latency information for ARM v6. It's rough and not yet hooked up. Right now  we are only using branch latency to determine if-conversion limits.

for ARM.  Patch by Sandeep Patel.

Move target independent td files from lib/Target/ to include/llvm/Target so they can be distributed along with the header files.

Restructure ARM code emitter to use instruction formats instead of addressing modes to determine how to encode instructions.
