9eb6b4d91b Fix APInt::operator*= so that it computes the correct result for large integers where there is unsigned overflow. Fix APFloat::toString so that it doesn't depend on the incorrect behavior in common cases (and computes the correct result in some rare cases). Fixes PR11086.

2acf638216 Take all of the invoke basic blocks and make the dispatch basic block their new
successor. Remove the old landing pad from their successor list, because it's
now the successor of the dispatch block. Now that the landing pad blocks are no
longer the destination of invokes, we can mark them as normal basic blocks
instead of landing pads.

This more closely resembles what the CFG is actually doing.

it with the new SjLj emitter stuff. This way there's no need to emit that
kind-of-hacky intrinsic.

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.
