Bill Wendling a9e3df7aa0 * Add support for encoding t_addrmode_s2 and t_addrmode_s1. They are the same as
t_addrmode_s4, but with a different scaling factor.

* Encode the Thumb1 load and store instructions. This involved a bit of
  refactoring (hi, Chris! :-). Some of the patterns became dead afterwards and
  were removed.

Jim Grosbach 51fdc47a11 ARMPseudoInst instructions should default to being considered a single 4-byte
instruction. Any that may be expanded otherwise by MC lowering should
override this value. rdar://8683274

Jim Grosbach a74c7ccd59 ARM PseudoInst instructions don't need or use an assembler string. Get rid of
the operand to the pattern.

just pretend to be.

Bill Wendling 345b48fcbd Add binary emission stuff for VLDM/VSTM. This reuses the
"getRegisterListOpValue" logic. If the registers are double or single precision,
the value returned is suitable for VLDM/VSTM.

Bill Wendling 3bd60eff26 - Remove dead patterns.

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.
