05a7453d54 MMX/SSE/SSE2 optimizations are now converted to full inline assembly code, 
aka avoid use of (possibly broken) GCC intrinsics. Add some SSE2 optimizations.
Translate VSLDOI, MFVSCR, MTVSCR instructions. AltiVec Fractal Carbon now
shows more than 1 GFlops performance!

e7d8a54e21 Enable high precision timings on POSIX systems supporting clock_nanosleep(). 
Since pthread_suspend_np() is not available to Linux (but NetBSD 2.0), thread
suspend is implemented likewise to boehm-gc.

9019e71cfc Preserve all necessary registers on interrupt, thus also permitting nested 
interrupts to occur. SheepShaver locks should now be reduced.

663facbf97 Fix native Linux/ppc with recent enough glibc that supports TLS; r2 is used 
in that case. Tell me if I broke other arches, e.g. r13 is no longer saved
in Video and Ethernet stubs, though it seems to be OK.

Colateral feature: SheepShaver should now run on Linux/ppc64 with relevant
32-bit runtime. Native Linux/ppc64 support is harder as low mem globals are
32-bit in mind and e.g. the TLS register there is %r13, %r2 is the TOC
(PowerOpen/AIX ABI)
