dfbc29a5a2 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.

c5f5626a29 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.

f1d93ca920 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.

599b531a96 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.

834df19452 Rework segment prefix emission code to handle segments 
in memory operands at the same type as hard coded segments.
This fixes problems where we'd emit the segment override after
the REX prefix on instructions like:
mov %gs:(%rdi), %rax

This fixes rdar://8127102.  I have several cleanup patches coming
next.

chunks aren't needed for this until the compiler starts generating these.  And
when that happens it will be more convenient for it to be a bool than a const
char*.

7db1e7a527 Teach the x86 floating point stackifier to handle COPY instructions. 
This pass runs before COPY instructions are passed to copyPhysReg, so we simply
translate COPY to the proper pseudo instruction. Note that copyPhysReg does not
handle floating point stack copies.

Once COPY is used everywhere, this can be cleaned up a bit, and most of the
pseudo instructions can be removed.
