1dd0086b06 Make "movdq2q" and "movq2dq" dependent upon having SSE2 because they use the
SSE2 registers as well as the MMX registers.

151ed61a2f Don't check TLI.getOperationAction. The FastISel way is to
just try to do the action and let the tablegen-generated code
determine if there is target-support for an operation.

7deb17108f Reinstate the x86-64 portion of r55190. When doing extloads into
64-bit registers from 16-bit and smaller memory locations, prefer
instructions that define the entire 64-bit register, to avoid
partial-register updates.
