304e143b16 Only spit out warning for functions that take pointers, not for sin and the like
Add more special case handling for stdio functions.  I feel dirty, how about you?

896481eaa8 No need to scan zero initializers. This should make DSA a bit faster.

68300db685 Add support for fopen/fclose. Specifically with fopen, we were marking all of the
operands as incomplete, though fopen is known to only read them.  This just adds
fclose for symmetry, though it doesn't gain anything.  This makes the dsgraphs for
181.mcf much more precise.

c3f5f7701f Instead of callign removeTriviallyDeadNodes on the global graph every time
removeDeadNodes is called, only call it at the end of the pass being run.
This saves 1.3 seconds running DSA on 177.mesa (5.3->4.0s), which is
pretty big.  This is only possible because of the automatic garbage
collection done on forwarding nodes.

15869aa2c7 All DSGraphs keep a reference to the targetdata they are created with. This is
used to eliminate the hard coded, hacked in, sparc specific, global TargetData.
Changing the TargetData used to actually match the code fixes problems, and
eliminates a crash.
