crypto: aesni-intel - Fix CTR optimization build failure with gas 2.16.1
Andrew Morton reported that AES-NI CTR optimization failed to compile
with gas 2.16.1, the error message is as follow:
arch/x86/crypto/aesni-intel_asm.S: Assembler messages:
arch/x86/crypto/aesni-intel_asm.S:752: Error: suffix or operands invalid for `movq'
arch/x86/crypto/aesni-intel_asm.S:753: Error: suffix or operands invalid for `movq'
To fix this, a gas macro is defined to assemble movq with 64bit
general purpose registers and XMM registers. The macro will generate
the raw .byte sequence for needed instructions.
