7a2e75185a This test stops after disassembling 1 instructions on 
darwin and, judging from the buildbots, Linux.
Removing it for now, but this is not the right fix,
Wesley please look at it.

00c5605efc Parse and remember discriminators in .loc line. I try to output them with 
another patch.
This lets us parse a bit more of the gcc 4.5 output.

an address is in a different block, get it into a register and go
from there.

29593ddf27 Have GVN simplify instructions as it goes. For example, consider 
"%z = %x and %y".  If GVN can prove that %y equals %x, then it turns
this into "%z = %x and %x".  With the new code, %z will be replaced
with %x everywhere (and then deleted).  Previously %z would be value
numbered too, which is a waste of time.  Also, while a clever value
numbering algorithm would give %z the same value number as %x, our
current one doesn't do so (at least I don't think it does).  The new
logic has an essentially equivalent effect to what you would get if
%z was given the same value number as %x, i.e. it should make value
numbering smarter.  While there, get hold of target data once at the
start rather than a gazillion times all over the place.

b565d1acf9 Add some missing isel predicates on def : pat patterns to avoid generating VFP vmla / vmls (they cause stalls). Disabling them in isel is properly not a right solution, I'll look into a proper solution next.

8b86287a06 When the definition of an address value is in a different block 
from the user of the address, fall back to just using the
address in a register instead of bailing out of fast-isel
altogether.

77cad43f26 Remove what looks like dead code in the production of debug lines. 
We only produce debug line information if we have seen a line directive, so
this code is dead. Also, if we want to be bug by bug compatible with
gas and sometimes produce "empty" .debug_line sections, this will
match the content produced by gas.
