Craig Topper 94ce535647 Make IC_VEX* not inherit from IC_*. Prevents instructions with no VEX form from disassembling to their non-VEX form. Also prevents weak filter collisons that were keeping valid VEX instructions from decoding properly. Make VEX_L* not inherit from VEX_* because the VEX.L bit always important. This stops packed int VEX encodings from being disassembled when specified with VEX.L=1. Fixes PR10831 and PR10806.

Dan Gohman 3767be9aee Revert r131152, r129796, r129761. This code is currently considered
to be unreliable on platforms which require memcpy calls, and it is
complicating broader legalize cleanups. It is hoped that these cleanups
will make memcpy byval easier to implement in the future.

Benjamin Kramer 6397051ece Don't drop alignment info on local common symbols.
- On COFF the .lcomm directive has an alignment argument.
- On ELF we fall back to .local + .comm

Jakob Stoklund Olesen 5dc87d0f4d Permit remat of partial register defs when it is safe.
An instruction may define part of a register where the other bits are
undefined. In that case, it is safe to rematerialize the instruction.
For example:

  %vreg2:ssub_0<def> = VLDRS <cp#0>, 0, pred:14, pred:%noreg, %vreg2<imp-def>

The extra <imp-def> operand indicates that the instruction does not read
the other parts of the virtual register, so a remat is safe.

This patch simply allows multiple def operands for the virtual register.
It is MI->readsVirtualRegister() that determines if we depend on a
previous value so remat is impossible.

Jakob Stoklund Olesen 6357fa2f06 Prevent remat of partial register redefinitions.
An instruction that redefines only part of a larger register can never
be rematerialized since the virtual register value depends on the old
value in other parts of the register.

This was fixed for the inline spiller in r138794.  This patch fixes the
problem for all register allocators, and includes a small test case.
