configure script is reportedly no longer crashing on FreeBSD when
SIGSEGV_SKIP_INSTRUCTION is set.

Backout "ignoresegv" support on FreeBSD/x86 for now. Unfortunately, the
configure script would hang whereas standalone testing will pass all tests.
Any idea why??
- Unix/sigsegv.cpp (ix86_skip_instruction): Add decoder for mozbl instruction.
  (SIGSEGV_REGISTER_FILE [FreeBSD/x86]): Note why we start at EDI offset
  rather than plain sigcontext pointer. i.e. I don't know sigset_t size
  beforehand and don't intend to.

Implement "ignoresegv" feature on FreeBSD/x86 (tested on FreeBSD 4.5)
- sigsegv.cpp (ix86_skip_instruction): Add decoder for movzwl instructions.
  (main): oddly, FreeBSD doesn't seem to let a write to a page if it is
  write-only. Aka. make the page readable too.

Implement "ignoresegv" feature on Darwin/ppc (tested on MacOS X)
- Unix/sigsegv.cpp (powerpc_decode_instruction): New.
  (get_fault_instruction [MacOS X]): Factorize code.
  (get_fault_instruction [Linux/m68k]): Don't use expression statement.
- README (ignoresegv): Add Darwin/ppc to list of supported platforms.

Implement "ignoresegv" feature on Linux/ppc:
- Unix/sigsegv.cpp (powerpc_skip_instruction): New from SheepShaver code.
- README (ignoresegv): Add Linux/ppc to list of supported platforms.

Implement the "ignoresegv" feature from SheepShaver. This is Unix-specific
so far. Target platform is currently Linux/x86.

- Add fault instruction recovery for Linux/ppc and siginfo_t handlers
