fixes a bunch of test-suite JIT failures on x86-64 in
-relocation-model=static mode.

Fix lfence and mfence encoding. These look like MRM5r and MRM6r instructions except they do not have any operands. The RegModRM byte is encoded with register number 0.

This unbreaks explicit reg vars inside JIT, which are
implemented in such hacky way :)

non_lazy_ptr mechanism on x86-64 Darwin JIT.  Fixes a bunch

model, except for external calls; this makes
addressing modes PC-relative.  Incomplete.

The assertion at the top of Emitter::runOnMachineFunction
was obviously bogus (always true) so I removed it.
If someone knows what the correct test should be to cover
all the various targets, please fix.

the need for a flavor operand, and add a new SDNode subclass,
LabelSDNode, for use with them to eliminate the need for a label id
operand.

Change instruction selection to let these label nodes through
unmodified instead of creating copies of them. Teach the MachineInstr
emitter how to emit a MachineInstr directly from an ISD label node.

This avoids the need for allocating SDNodes for the label id and
flavor value, as well as SDNodes for each of the post-isel label,
label id, and label flavor.

This eliminates the need for several awkward casts, including
the last dynamic_cast under lib/Target.

Infrastructure for getting the machine code size of a function and an instruction. X86, PowerPC and ARM are implemented

Fix x86-64 encoding bug. REX prefix must always follow 0x0F prefix. For example, extractps in 64bit mode: 66 REX 0F 3A 17, not 66 0F 3A REX 17.

Add lock prefix support to x86.  Also add the instructions necessary for the atomic ops.  They are still marked pseudo, since I cannot figure out what format to use, but they are the correct opcode.

Evan, please review the comments I added to getNumDefs to make sure

that it is cheap and efficient to get.

Move a variety of predicates from TargetInstrInfo into 
TargetInstrDescriptor, which makes it much easier to query a predicate
when you don't have TII around.  Now you can use MI->getDesc()->isBranch()
instead of going through TII, and this is much more efficient anyway. Not
all of the predicates have been moved over yet.

Update old code that used MI->getInstrDescriptor()->Flags to use the
new predicates in many places.
