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!):

Add support for branches (based loosely on X86/InstSelectSimple).
Add support for not visiting phi nodes in the first pass.
Add support for loading bools.
Flesh out support for stores.

%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.

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.)

Disable the code that copies long constants to registers - it looks fishy.
Implement some simple casts: integral, smaller than longs, and equal-width
or narrowing only.

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.

the debugging functions that call "dot". These fixed settings have
various problems: for example, the fixed size that is set in the graph
traits classes is not appropriate for turning the dot file into a PNG,
and if TrueType font rendering is being used, the 'Courier' TrueType font
may not be installed. It seems easy enough to specify these things on the
command line, anyhow.

constant pool member's name.
This is intended to address Bug 333.
Also, fix an anachronistic usage of "M" as a parameter of type Function *.

fills in a ToolArgs vector in the AbstractInterpreter if it is set. This
ToolArgs vector is used to pass additional arguments to LLI and/or LLC.
This is intended to address Bug 40.
Also, make -debug-only=toolrunner work for the LLC and CBE
AbstractInterpreters.
