[issue1346] [PATCH] Fix some minor inline assembly for llvm/clang compatibility

["Alex Hornung \(via DragonFly issue tracker\)" <sinknull@xxxxxxxxxxxxxxxxxxxxxxx>]

New submission from Alex Hornung <ahornung@gmail.com>:

1) remove uses of __label__, which is not supported by llvm/clang and is not
needed for either gcc or llvm/clang.

2) remove uses of register type var __asm("ecx") and other variable
register-binding as it is not supported by llvm/clang and is superfluous. By
specifying that the variable content should go into ecx in the clobber list, the
current use is not needed.

3) add an ugly hack, conditionalized on __clang__, to allow correct
compilation of atomic_intr_cond_try(). This hack should be removed once
http://llvm.org/bugs/show_bug.cgi?id=3812 is solved. It is conditionalized on
__clang__ define because it is not a valid syntax for gcc.
