APInt.  Be certain to set the integer bit in an x87 extended-precision

It gets its own implementation totally divorced from the (presumably
performance-sensitive) routines which parse into a uint64_t.

Add APInt::operator|=(uint64_t), which is situationally much better than
using a full APInt.

node is always guaranteed to have a particular type

us to use implied types for a broad range of nodes, even
target specific ones.

Extracting the low element of a vector is now done with EXTRACT_SUBREG,
and the zero-extension performed by load movss is now modeled with
SUBREG_TO_REG, and so on.

Register-to-register movss and movsd are no longer considered copies;
they are two-address instructions which insert a scalar into a vector.
