Fix SAHF_SETO_PROFITABLE code for x86-64 platforms.
...
This was only an experiment. Improvement was marginal: only +3% on AMD64
(an Athlon 64 3200+). However, it may be interesting to test it on EM64T
(e.g. newer P4s) since an older P3/800, hence in 32-bit mode, got a +15%
improvement in Speedometer 4 benchmarks.
Rationale: lahf/seto sequences avoid load/stores to the stack (push/pop)
and it was thus hoped to be faster.
Anyhow, SAHF_SETO_PROFITABLE can only be enabled manually at this time.
Edit your generated Makefile for testing, but first make sure your CPU
supports lahf in 64-bit mode (lahf_lm flag in /proc/cpuinfo).

- Fix SPARC Store Doubleword transfer_size in decoder.
...
- In the instruction skipper code, add a huge kludge (trampoline) to forcibly
zero out %global registers when requested. Otherwise, Solaris/SPARC turned
out to use %g1 during signal handling, and the zero we could have written
to there vanished. This assumes [%sp-8] is valid to use (ABI states data
below %sp is undefined though)

JIT generated code is not guaranteed to be leaf, e.g. there could be a call

to a generic instruction handler (untranslated code). This caused problems
