b66f18486a Constrain both operands on MOVZX32_NOREXrr8.
This instruction is explicitly encoded without an REX prefix, so both
operands but be *_NOREX.

Also add an assertion to copyPhysReg() that fires when the MOV8rr_NOREX
constraints are not satisfied.

This fixes a miscompilation in 20040709-2 in the gcc test suite.

186ffac4d3 Improve ARM assembly parser diagnostic for unexpected tokens.
Consider:
  mov r8, r11 fred

Previously, we issued the not very informative:
x.s:6:1: error: unexpected token in argument list

^

Now we generate:
x.s:5:14: error: unexpected token in argument list
  mov r8, r11 fred
              ^

3f329cb781 Teach GVN to also propagate switch cases. For example, in this code
switch (n) {
    case 27:
      do_something(x);
    ...
  }
the call do_something(x) will be replaced with do_something(27).  In
gcc-as-one-big-file this results in the removal of about 500 lines of
bitcode (about 0.02%), so has about 1/10 of the effect of propagating
branch conditions.

25f6dfd108 Revert part of r141274. Only need to change encoding for xchg %eax, %eax in 64-bit mode. This is because in 64-bit mode xchg %eax, %eax implies zeroing the upper 32-bits of RAX which makes it not a NOP. In 32-bit mode using NOP encoding is fine.

then jumps to the correct call site via a jump table.
