target-i386: implement lzcnt emulation

lzcnt is a AMD Phenom/Barcelona added instruction returning the
number of leading zero bits in a word.
As this is similar to the "bsr" instruction, reuse the existing
code. There need to be some more changes, though, as lzcnt always...

target-i386: add RDTSCP support

RDTSCP reads the time stamp counter and atomically also the content
of a 32-bit MSR, which can be freely set by the OS. This allows CPU
local data to be queried by userspace.
Linux uses this to allow a fast implementation of the getcpu()...

SYSENTER/SYSEXIT IA-32e implementation (Alexander Graf).

On Intel CPUs, sysenter and sysexit are valid in 64-bit mode. This patch
makes both 64-bit aware and enables them for Intel CPUs.
Add cpu save/load for 64-bit wide sysenter variables.
