Move asm label functions from tccasm.c to tccgen.c

* Move functions parse_asm_str and asm_label_instr from tccasm.c to
  tccgen.c
* Remove CONFIG_TCC_ASM_LABEL macro as asm label are available on all
  archs.
See:
http://lists.nongnu.org/archive/html/tinycc-devel/2010-09/msg00026.html
for the rationale.
