Summary0000293: asm_fast grades do not work with GCC 4.8
DescriptionThe asm_fast grades do not work with GCC 4.8 on Fedora 19 x86-64 (and probably elsewhere).
(The configure test for gcc labels is failing due to a segmentation fault on my system.)
This was with Mercury 13.05.

This seems to be caused by the option -ftree-dominator-opts.

I've committed a fix for this (i.e. compile with -fno-tree-dominator-opts). I would also not that
compiling with -fno-omit-frame-pointer is also a possible fix. I'll keep this bug open until I've decided
what the best fix is.

We compile with -fno-tree-dominator-opts in this case. (Also affects GCC 4.9 and 5.)
