[PATCH resend 00/19] Emulator speedups for 3.17

[Paolo Bonzini]

These are the emulator speedup patches that have survived autotest
and kvm-unit-tests.  I dropped the patches for direct access to
memory operands because they caused a failure in vmx.flat.

These patches have been in kvm/queue for a while, but I've always
left them out of kvm/next because they hadn't undergone full review.
Since three months have passed, I'll include them in the next push to
kvm/next to give them more exposure and to prepare for 3.17.
