  Log Message:
  -----------
  re-add PASM output to imcc, re-add imcpasm tests

one new IMCCompiler api method: set_to_pasm
remove static output in imcc/instructions.c
change Parrot::Test pir_2_pasm mthod to use -d1000, which is equivalent
to pasm output (just to stderr)
detect .pasm -o outfile extension
add __builtin_expect LIKELY/UNLIKELY macros (WIP)
