Instead of unconditionally copying all phi node values into temporaries for
all successor blocks, generate code that will determine what successor
block will be called and then copy only those phi node values needed by
the successor block.
This seems to cut down namd execution time from being 8% higher than GCC to
4% higher than GCC.

0->field, which is illegal. Now we print ((foo*)0)->field.
The second hunk is an optimization to not print undefined phi values.

Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

Note that this indicates a serious problem with the way we are emitting varargs,
but this should not be properly fixed until after 1.3.
This patch SHOULD go into 1.3.

glibc 'nan' function because the initializer is not a string. This breaks when used in a global
initializer. Try compiling this testcase for example:
%X = global float <some nan value>

that we REALLY don't want in the CBE code.
With this fix, the CBE passes all of the MultiSource tests on cygwin that
it does on linux. Yaay!

few days. Apparently the old symbol table used to auto rename collisions in
the type symbol table and the new one does not. It doesn't really make sense
for the new one to do so, so we just make the client do it.

FindUsedTypes manipulation stuff out to be a seperate pass, and make the
main CWriter be a function pass now!

been using the default target data layout object to lower malloc instructions,
causing us to allocate more memory than we needed! This could improve the
performance of the CBE generated code substantially!

(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's
dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in
the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.

Functions with linkonce linkage are declared with weak linkage.
Global floating point constants used to represent unprintable values
(such as NaN and infinity) are declared static so that they don't interfere
with other CBE generated translation units.

longer was getting this #include, it always fell back on the less precise
floating point initializer values, causing some testsuite failures.

hacks can be banished. Also, this gives us the opportunity to emit special code
for the setjmp/longjmps which alows the elimination of one GCC warning for every
setjmp/longjmp site (which is often THOUSANDS in C++ programs). Yaay!
