normal cbb79f0472 signal.c: avoid repeated disable/enable interrupt
We only install system-level signal handlers during init (before any
threads or user code is running), so there's no need to repeatedly
enable/disable the interrupts at that time.  We also do not change
system-level sig handlers once user-level code is running.

This saves about 20 syscalls at startup and makes the executable
smaller (numbers from 32-bit x86):

shyouhei 2c770d676c * signal.c (rb_atomic_t): GCC (of at least recent versions)
has  ubiquitos  support  for  atomic  operations.   On  that
  compiler a C  program can isse a memory  barrier using these
  dedicated  instructions.  According to  the GCC  manual they
  cargo culted  this feature form  the Itanium ABI  so chances
  are that  other compilers  could also support  this feature.
  But so far GCC is the  only compiler that I know to have it.
