5de3b8b262 Change the callgraph representation to store the callsite along with the 
target CG node.  This allows the inliner to properly update the callgraph
when using the pruning inliner.  The pruning inliner may not copy over all
call sites from a callee to a caller, so the edges corresponding to those
call sites should not be copied over either.

This fixes PR827 and Transforms/Inline/2006-07-12-InlinePruneCGUpdate.ll

c4998a0138 Fix Transforms/DeadArgElim/2006-06-27-struct-ret.ll. -deadargelim should not 
remove the struct return argument of a csret function, even if it is obviously
dead.

1fc4025a9c More libcall transformations:

printf("%c", c) -> putchar(c)
Also fixed fprintf(file, "%c", c) -> fputc(c, file)

a9cdcca3c3 Add a simple pass to make sure that all (non-library) calls to malloc and free 
are visible to analysis as intrinsics.  That is, make sure someone doesn't pass
free around by address in some struct (as happens in say 176.gcc).

This doesn't get rid of any indirect calls, just ensure calls to free and malloc
are always direct.

33081b4648 Make this more efficient in the following ways: 
1. Do not statically construct a map when the program starts up, this
   is expensive and cannot be optimized.  Instead, create a list.
2. Do not insert entries for all function in the module into a hashmap
   that lives the full life of the compiler.

0d4ebfc15b Several non-functionality changing changes: 
1. Use the varargs version of getOrInsertFunction to simplify code.
2. remove #include
3. Reduce the number of #ifdef's.
4. remove extraneous vertical whitespace.

ade182125f For PR696: 
Don't do floor->floorf conversion if floorf is not available. This checks
the compiler's host, not its target, which is incorrect for cross-compilers
Not sure that's important as we don't build many cross-compilers.

175613adf6 Improve ResolveFunctions to: 
a) use better local variable names (OldMT -> OldFT) where "M" is used to
   mean "Function" (perhaps it was previously "Method"?)
b) print out the module identifier in a warning message so that it is
   possible to track down in which module the error occurred.

Add support for specifying alignment and size of setjmp jmpbufs.

No targets currently do anything with this information, nor is it presrved
in the bytecode representation.  That's coming up next.

11e26b52b2 When a function takes a variable number of pointer arguments, with a zero 
pointer marking the end of the list, the zero *must* be cast to the pointer
type.  An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.

The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.

45517baf9f Add an option to this pass. If it is set, we are allowed to internalize 
all but main.  If it's not set, we can still internalize, but only if an
explicit symbol list is provided.
