57ea4daa2e do not dereference an extra layer of pointers to determine if an external
call can modify a memory location.  This fixes

5ceaf630ab Fix a major problem with global variable initializers. This could cause
us to have stuff pointing to the null pointer, which makes no sense
(the null ptr is an ssa value, not the null object)

813ef90a12 Handle "known" external calls context sensitively, add support for realloc
and a couple of other functions that are important.

external functions.  Teach it about a few important ones.

4b688a1c70 This mega patch converts us from using Function::a{iterator|begin|end} to
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

This patch is contributed by Gabor Greif, thanks!

43c0372c0b 'Pass' should now not be derived from by clients. Instead, they should derive
from ModulePass.  Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.

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/.

818ac2d5e2 Fix a bug that caused the pass to go into infinite loops on trivial testcases.
This is fallout of the Bug 122 changes.
