X86: Mark JMP{32,64}[mr] as requires 32-bit/64-bit mode. They are the same
...
instruction, we only want to allow the one for the current subtarget.
- This also fixes suffix matching for jmp instructions, because it eliminates
the ambiguity between 'jmpl' and 'jmpq'.

Teach computeRegisterProperties() to compute "representative" register class for legal value types. A "representative" register class is the largest legal super-reg register class for a value type. e.g. On i386, GR32 is the rep register class for i8 / i16 / i32; on x86_64 it would be GR64.
...
This property will be used by the register pressure tracking instruction scheduler.

Revert r108369, sorting llvm.dbg.declare information by source position,
...
since it doesn't work for front-ends which don't emit column information
(which includes llvm-gcc in its present configuration), and doesn't
work for clang for K&R style variables where the variables are declared
in a different order from the parameter list.
Instead, make a separate pass through the instructions to collect the
llvm.dbg.declare instructions in order. This ensures that the debug
information for variables is emitted in this order.

Allow x87 FP registers to be alive globally in a function.
...
FP_REG_KILL instructions are still inserted, but can be disabled by passing
-live-x87 to llc. The X87FPRegKillInserterPass is going to be removed shortly.
CFG edges are partioned into bundles where the x87 stack must be allocated
identically. Code is insertad at the end of each basic block that shuffles the
live FP registers to match the outgoing bundles expectations.
This fix is in preparation for some upcoming register allocator improvements
that may extend the live range of registers beyond a basic block, similar to
LICM. It also provides a nice runtime speedup if you are building with
-mfpmath=387.

define void @foo() {
entry:
unreachable
}
$ llc -o - t.ll -relocation-model=pic -disable-fp-elim -unwind-tables
.section __TEXT,__text,regular,pure_instructions
.globl _foo
.align 4, 0x90

## BB#0: ## %entry
pushq %rbp

movq %rsp, %rbp

The unwind tables then have bad data in them causing all sorts of problems.

Don't merge uses when they are targetting fixup sites with

different widths. In a use with a narrower fixup, formulae
may be wider than the fixup, in which case the high bits

them for uses with wider fixups.
This fixes PR7618, though the testcase is too large for a
reasonable regression test, since it heavily dependes on
hitting LSR's heuristics in a certain way.
