279d8e8e2d Switch this from using an std::map to using a DenseMap. This speeds up
phi-elimination from 0.6 to 0.54s on kc++.

3fb5488b5e Use a new VRegPHIUseCount to compute uses of PHI values by other phi values
in the basic block being processed.  This fixes PhiElimination on kimwitu++
from taking 105s to taking a much more reasonable 0.6s (in a debug build).

8b57a31ff4 Now that we use an ilist of machine instructions, iterators are more robust
than before.  Because this is the case, we can compute the first non-phi
instruction once when de-phi'ing a block.  This shaves ~4s off of
phielimination of _Z7yyparsev in kimwitu++ from 109s -> 105s.  There are
still much more important gains to come.

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).

7cc5d0f106 Add support for widening integral casts.
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!):

       BB
   cond. branch
     /         /          R1=1    R2=0
     \      /

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.)

allows us to compile:

store float 10.0, float* %P

into:
        mov DWORD PTR [%EAX], 1092616192

instead of:

.CPItest_0:                                     # float 0x4024000000000000
.long   1092616192      # float 10
