Hi!

This is http://gcc.gnu.org/ml/gcc-patches/2010-08/msg01475.html
patch, just tiny bit updated so that it applies against current
trunk and doesn't attempt to put ASM_OPERANDS into var-tracking
tables (which sometimes pessimizes things, if var-tracking
chooses ASM_OPERANDS instead of some other expression, as
ASM_OPERANDS will be always necessarily rejected by dwarf2out
while some other expression perhaps could work).

Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

	Jakub
