Message:

VMM/HMVMX: More hmR0VmxExportHostSegmentRegs tweaking. Moved all the vmwrites to one block. Added assembly helper for windows so we don't make a whole bunch of ASMGetCS/SS/DS/ES/FS/GS/TR calls to two instruction external assembly routines. Assuming that LDT selectors are rare, did an optimized code path for that (the assembly output look much better with MSC). [build fix]
