x86/paravirt: selectively save/restore regs around pvops calls
Impact: Optimization
Each asm paravirt-ops call says what registers are available for
clobbering. This patch makes use of this to selectively save/restore
registers around each pvops call. In many cases this significantly
shrinks code size.
