[PATCH 00/13] jump label v9

[Jason Baron <jbaron@redhat.com>]

Hi,

updates for -v9:

*build time detection of gcc 'asm goto' feature via scripts/gcc-goto.sh,
which basically tries to compile a simple 'asm goto' c program, and if
it succeeds we define CC_HAVE_ASM_GOTO. In this way we detect the 4.5 gcc
feature if its backported, as it has been done to 4.4 gcc in fedora.

*misc cleanups and simplifications.

thanks,

-Jason
