67f0ebc5c6 Added a support for inserting new MBBs into the numbering. 
Unlike insertMachineInstrInMaps this does not guarantee live intervals will
remain correct. The caller will need to manually update intervals to account
for the changes made to the CFG.

a5c1c795a2 have the mc lowering process handle a few tail call forms, lowering them to 
jumps where possible and turning the TAILCALL marker in the instruction
asm string into a proper comment.

This eliminates a FIXME and is on the path to finishing:
rdar://7639610 - eliminate encoding and asm info for TAILJMPd TAILJMPr TAILJMPn, etc.

However, I can't eliminate the encodings for these instructions because the JIT
still exists and has its own copy of the encoder, sigh.

7e6e4dd058 Re-apply bottom-up fast-isel, with fixes. Be very careful to avoid emitting 
a DBG_VALUE after a terminator, or emitting any instructions before an EH_LABEL.

dd02fe62a2 Reenable DAG combining for vector shuffles. It looks like it was temporarily 
disabled and then never turned back on again.  Adjust some tests, one because
this change avoids an unnecessary instruction, and the other to make it
continue testing what it was intended to test.

49ac65543c Change LEA to have 5 operands for its memory operand, just 
like all other instructions, even though a segment is not
allowed.  This resolves a bunch of gross hacks in the 
encoder and makes LEA more consistent with the rest of the
instruction set.

No functionality change.
