neel e5110c0076 Do a proper emulation of guest writes to MSR_EFER.
- Must-Be-Zero bits cannot be set.
- EFER_LME and EFER_LMA should respect the long mode consistency checks.
- EFER_NXE, EFER_FFXSR, EFER_TCE can be set if allowed by CPUID capabilities.
- Flag an error if guest tries to set EFER_LMSLE since bhyve doesn't enforce
  segment limits in 64-bit mode.
