Delete 108 lines of ASM from vmx_enter_guest() that predated lots
of later enhancements, removing the save/restore of flags, selectors,

selectors and MSRs are auto-restored. The FSBASE, GSBASE, and
KERNELGSBASE MSRs just need the correct values set with vmwrite()

Note: this changes the format of the sc_fpstate data in the signal context to possibly be in compressed format: starting now we just guarantee that that state is in a format understood by the XRSTOR instruction of the system that is being executed on. At this time, passing sigreturn a corrupt sc_fpstate now results in the process exiting with no attempt to fix it up or send a T_PROTFLT trap. That may change. prodding by deraadt@ issues with my original signal handling design identified by kettenis@ lots of base and ports preparation for this by deraadt@ and the libressl and ports teams ok deraadt@ kettenis@
