a407338e12 Fix a fairly serious pessimizaion that was preventing us from efficiently 
compiling things like 'add long %X, 1'.  The problem is that we were switching
the order of the operands for longs even though we can't fold them yet.

b37490a331 Patch to fix PR337. Make sure to mark all aliased physical registers as used 
when we see a read of a register.  This is important in cases like:

AL = ...
AH = ...

   = AX

The read of AX must make both the AL and AH defs live until the use.

b417772e42 Changes to make the Stacker Stack use 64 bit values. This *should* get 
around the problem with Stacker on Solaris because the Stack can handle
64-bit entries (pointer sized).

Flesh out the SetCC support... which currently ends in a little bit
of unfinished code (which is probably completely hilarious) for
generating the condition value splitting the basic block up into 4
blocks, like this (clearly a better API is needed for this!):

e3b3e333b0 Implement folding of GEP's like: 
%tmp.0 = getelementptr [50 x sbyte]* %ar, uint 0, int 5         ; <sbyte*> [#uses=2]
        %tmp.7 = getelementptr sbyte* %tmp.0, int 8             ; <sbyte*> [#uses=1]

together.  This patch actually allows us to simplify and generalize the code.

e99247512f Allow the user to set the LLVMINTERP environment variable as a workaround, for 
when they have to run a gccld shell script without having lli in their path.
This is intended to address Bug 289.

Also, emit the traditional syntax ${1+"$@"} for passing all of a shell script's
args to a subprocess. If you have arguments that have spaces in them, $* will
not preserve the quoting (i.e., the quoted string "foo bar" as an argument will
end up as two arguments "foo" "bar" to lli.)

store float 10.0, float* %P

instead of:

.CPItest_0:                                     # float 0x4024000000000000

d055a56886 Use the new commandline flag to allow us to call bugpoint like this: 
bugpoint ... --tool-args -enable-correct-eh-support -regalloc=linearscan --args -- -foo

So that tool-args option gets the -enable-correct-eh-support -regalloc=linearscan flags instead of bugpoint.

2d7c5ae892 Fix for PR#330. 
When looking at getelementptr instructions, make sure to use a forwarded
type.  We want to do this because a DerivedType may drop its uses and then
refine its users, who may then use another user who hasn't been refined yet.
By getting the forwarded type, we always ensure that we're looking at a
Type that isn't in a halfway refined state.

Now, I should be able to put this stuff in PATypeHandle, but it doesn't work
for some reason.  This should do for now.
