b6faf65215 Multiclassify the LDR/STR encoding patterns. The only functionality difference 
is the addition of the FoldableAsLoad & Rematerializable flags to some of the
load instructions. ARM has these flags set for them.

f4caf69720 The tLDR et al instructions were emitting either a reg/reg or reg/imm 
instruction based on the t_addrmode_s# mode and what it returned. There is some
obvious badness to this. In particular, it's hard to do MC-encoding when the
instruction may change out from underneath you after the t_addrmode_s# variable
is finally resolved.

The solution is to revert a long-ago change that merged the reg/reg and reg/imm
versions. There is the addition of several new addressing modes. They no longer
have extraneous operands associated with them. I.e., if it's reg/reg we don't
have to have a dummy zero immediate tacked on to the SDNode.

There are some obvious cleanups here, which will happen shortly.

4711d5cda3 Remove the rest of the *_sfp Neon instruction patterns. 
Use the same COPY_TO_REGCLASS approach as for the 2-register *_sfp instructions.
This change made a big difference in the code generated for the
CodeGen/Thumb2/cross-rc-coalescing-2.ll test: The coalescer is still doing
a fine job, but some instructions that were previously moved outside the loop
are not moved now.  It's using fewer VFP registers now, which is generally
a good thing, so I think the estimates for register pressure changed and that
affected the LICM behavior.  Since that isn't obviously wrong, I've just
changed the test file.  This completes the work for Radar 8711675.

1e6f59608b Use COPY_TO_REGCLASS instead of pseudo instructions for Neon FP patterns. 
Jakob Olesen suggested that we can avoid the need for separate pseudo
instructions here by using COPY_TO_REGCLASS in the patterns.  The pattern
gets pretty ugly but it seems to work well.  Partial fix for Radar 8711675.

c266600bec In Thumb2, direct branches can be encoded as either a "short" conditional branch with a null predicate, or 
as a "long" direct branch.  While the mnemonics are the same, they encode the branch offset differently, and
the Darwin assembler appears to prefer the "long" form for direct branches.  Thus, in the name of bitwise
equivalence, provide encoding and fixup support for it.
