This introduces a small regression on the generated code
quality in the case we are just computing addresses, not
loading values.

Will work on it and on X86-64 support.

Re-apply 66024 with fixes: 1. Fixed indirect call to immediate address assembly. 2. Fixed JIT encoding by making the address pc-relative.

Fix MachineCodeEmitter to use uintptr_t instead of intptr_t. This avoids some overflow issues. Patch by Thomas Jablin.

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.

Make MachineInstr::getDesc return a reference instead
of a pointer, since it can never be null.
