719fd86bdc Allow constant folding of GEP instructions, even if we don't do a whole lot yet.
Fold ConstExpr casts better
castToPointer shouldn't be forced to return a constantpointer

b5027095e5 - Eliminated the deferred symbol table stuff in Module & Function, it really
wasn't an optimization and it was causing lots of bugs.

46b6e30fef Eliminate the concept of a deferred symbol table. The optimization really isn't,
and it causes obscure bugs to show up in passes.

82f54dca49 - Change Function's so that their argument list is populated when they are
constructed.  Before, external functions would have an empty argument list,
    now a Function ALWAYS has a populated argument list.

fdf2ca9468 - Rename Instruction::First*Op to *OpsBegin, and Num*Ops to *OpsEnd to
reflect the fact that it's a range being defined.

266bacb650 - Make Value::replaceAllUsesWith work with constants correctly. This fixes
bug FuncResolve/2002-08-19-ResolveGlobalVars.ll and gzip looks better.

0acdba0025 - Add new Constant::replaceUsesOfWithOnConstant which has an end result
similar to User::replaceUsesOfWith but actually does the right thing for
    constants.

88de60dd26 Fix NASTY N^2 behavior that was causing the gzip benchmark to take forever to
assemble.  Now we scan the use-list from the back when removing users instead
of from the front.

85ba0832e5 Fix a nasty problem with dominance calculation for unreachable blocks.
If we had a CFG that look like Entry -> B, Unreachable -> B, then we would
not correctly determine that Entry dominated B, because Entry did not
apparently dominate "unreachable".  This patch fixes this by making the entry
node dominate all blocks, including unreachable ones.
