Don't use * in XFAIL line unless you want it to XFAIL on everything. I don't believe you can use true regular expressions here. It will just look for those keywords. Please test this on sparc and see if they still are xfailed.

Missed the case where alloca is used but the stack size (not including callee-saved portion) is zero. Thanks Dan.

Move tests that have C/C++ sources into the appropriate directory. This
allows them to be selected for testing based on whether llvm-gcc is
present or not.

This also avoids a fork bomb from the llvm-top/build script which
doesn't know how to handle cycles in the dependence graph.

llvm-gcc build to succeed. Without this change it fails in libstdc++
compilation. This causes no regressions in dejagnu tests. However, 
someone who knows this code better might want to review it.

have an error, and refector out the code for binary operators into
ConstantFoldBinaryFP and use it for all binary floating-point operations
which may have an error. These functions still rely exclusively on errno
to detect errors though.

First teach instcombine that sign bit checks only demand the 
sign bit, this allows simplify demanded bits to hack on 
expressions better.

Second, teach instcombine that ashr is useless if only the
sign bit is demanded.
