Implement a small optimization to handling of GEP's that are equivalent to casts.
This results in substantially reduced collapsing for some testcases

I can't believe the incompetence of the people I have to deal with around here.
These fools don't even wrap code at 80 columns.

Oh wait, _I_ wrote that.  That explains a lot!!

Bugz come in, bugs go out

Fix PR 110: the constant folding code assumes that if something is not a
constant expression, but is of (for example) ubyte type, then it is a
ConstantUInt.  This was not true for placeholders.

This is obviously illegal C++ code, but was apparently accepted by 3.3

Give props to Reid Spencer for the namespacification work.

Brian implemented the vaarg instruction in the interpreter.

Removed link from the docs index too.

As the comments indicate, this is a temporary, repulsive, hack

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9982 91177308-0d34-0410-b5e6-96231b3b80d8

Implement feature: InstCombine/2003-11-13-ConstExprCastCall.ll

Instcombine should promote this, and because it isn't, we are failing poolalloc tests

Trying to get the dsgraph for an external function is bad for DSA's health

NEW testcase for PR84 :(

Change LLI's internal representation of va_list to a pointer to the next
argument to be returned by va_arg. This allows va_lists to be passed
between different LLVM procedures (though it is unlikely that an LLI
va_list would make sense to an external function, except by chance.)
