120K of memory for namd, a medium sized program.

Move include/Config and include/Support into include/llvm/Config,

Remove mem leaks resulting from not freeing parse strings.

Provide parsing for the target triple and dependent libraries.

Provide new tokens for target triples and dependent libraries.

- Minimize redundant isa<GlobalValue> usage
- Correct isa<Constant> for GlobalValue subclass
- Remove tabs
- Fix coments refering to ConstantPointerRef

* Simplify a lot of code because type's cannot be in function symbol tables
* Fix memory leaks in handling of redefined function prototypes
* Don't use SymbolTable directly for stuff that we can go through the Module
  for.
* Fix some minor bugs on obscure testcases like:
      test/Feature/globalredefinition.ll
* Do not create GlobalVariable objects for forward referenced Functions!
* When forward referencing a function in a constant expression, do not create
  a placeholder, add a bunch of references to it, then turn around and
  replaceAllUsesOfWith on it with a new global, deleting the placeholder.
  Instead, when we find the real definition of the global, just use the
  placeholder instead of creating a new object.

This substantially simplifies the asmwriter and should even speed it up on
cases heavy in constantexprs (like C++, Java, MSIL)...

llvm-svn: 14830

  replaceAllUsesWith'ing any forward references, just use the forward
  reference if it exists.

This introduces GetForwardRefForGlobal, which will eventually completely
replace the horrible DeclareNewGlobalValue function.

to substantially simplify the result.  In particular, we no longer create
GlobalVariables and then immediately destroy them when they are duplciate
definitions.

The real point of this patch though is that it gets us closer to the
DeclareNewGlobalValue calls...

functions multiple times, expecting them to be merged.  This should be fixed
in the CFE, then here.

This gives us only a single call site for setValueNameMergingDuplicates.
The next stage is the start merging them together.

llvm-svn: 14811

Since the stupid '%X = const int 4' thing is gone, we can now simplify
setValueNameMergingDuplicates a bit more.

for a basic block, use it when the block is defined instead of deleting it
and creating a new one.  Also, only create at most ONE forward reference
for any block, instead of one for each forward reference.

forward reference blocks if they have been created (instead of creating a new
block, replaceAllUsesOfWith, then nuking the placeholder).   This is not yet
implemented.

the funciton symbol table to check for conflicts instead of having to
keep a shadow named LocalSymtab.  Totally eliminate LocalSymtab.  Verified
that this did not cause a regression on the testcase for PR107.

  1. Split setValueName into two separate functions, one that is only used
     at function scope and doesn't have to deal with duplicates, and one
     that can be used either at global or function scope but that does deal
     with conflicts.  Conflicts were only in there because of the crappy old
     CFE and probably should be entirely eliminated.
  2. Insert BasicBlock's into the parent functions when they are created
     instead of when they are complete.  This effects name lookup (for the
     better), which will be exploited in the next patch.
