Daniel Dunbar 4cc1feff4f Remove some dead code.

David Goodwin 3b9c52c5c1 Initial support for single-precision FP using NEON. Added "neonfp" attribute to enable. Added patterns for some binary FP operations.

Daniel Dunbar 31b44e8f6c Normalize Subtarget constructors to take a target triple string instead of 
Module*.

Also, dropped uses of TargetMachine where unnecessary. The only target which
still takes a TargetMachine& is Mips, I would appreciate it if someone would
normalize this to match other targets.

Evan Cheng 6ab54fdb0a Fix Thumb2 function call isel. Thumb1 and Thumb2 should share the same 
instructions for calls since BL and BLX are always 32-bit long and BX is always
16-bit long.

Also, we should be using BLX to call external function stubs.

Bob Wilson 482495695e Use thumb2 for ARM architectures V6T2 and later. Fix a bug in checking 
for "thumb" and add a check for V6T2.

Bob Wilson 4582530a2c For Darwin on ARMv6 and newer, make register r9 available for use as a 
caller-saved register.

Anton Korobeynikov 77d1943637 The attached patches implement most of the ARM AAPCS-VFP hard float 
ABI. The missing piece is support for putting "homogeneous aggregates"
into registers.

Patch by Sandeep Patel!

Evan Cheng 0ee0da841d ARM target now also recognize triplets like thumbv6-apple-darwin and set thumb mode and arch subversion. Eventually thumb triplets will go way and replaced with function notes.
