#pragma comment(option,"-..."), bitfields test, etc...

Browse Source 
tccpp.c:
* #pragma comment(option,"-some-option")
  to set commandline option from C code.  May work only
  for some options.
libtcc.c:
* option "-d1..9": sets a 'g_debug' global variable.
  (for development)
tests2/Makefile:
* new make targets: tests2.37 / tests2.37+
  run single test from tests2,  optionally update .expect
* new variable GEN-ALWAYS to always generate certain .expects
* bitfields test
tccgen.c:
* bitfields: fix a bug and improve slightly more
* _Generic: ignore "type match twice"
