with this commit the callee moves to the end of
the operand array (from the start) and the call
arguments now start at index 0 (formerly 1)
this ordering is now consistent with InvokeInst
this commit only flips the switch,
functionally it is equivalent to
r101465
I intend to commit several cleanups after a few
days of soak period

Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.

I have audited all getOperandNo calls now, fixing
hidden assumptions. CallSite related uglyness will
be eliminated successively.
Note this patch has a long and griveous history,
for all the back-and-forths have a look at
CallSite.h's log.

This time I did a self-hosted bootstrap on Linux x86-64,

Modules and ModuleProviders. Because the "ModuleProvider" simply materializes
GlobalValues now, and doesn't provide modules, it's renamed to
"GVMaterializer". Code that used to need a ModuleProvider to materialize
Functions can now materialize the Functions directly. Functions no longer use a
magic linkage to record that they're materializable; they simply ask the
GVMaterializer.
Because the C ABI must never change, we can't remove LLVMModuleProviderRef or
the functions that refer to it. Instead, because Module now exposes the same
functionality ModuleProvider used to, we store a Module* in any
LLVMModuleProviderRef and translate in the wrapper methods. The bindings to
other languages still use the ModuleProvider concept. It would probably be
worth some time to update them to follow the C++ more closely, but I don't
intend to do it.

This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare.
It also strips old llvm.dbg.declare intrinsics that did not pass metadata as the first argument.

Among other benefits, this doesn't leak the SmallPtrSet, has the verifier
code in the verifier pass, actually does the verification at the end,
and is considerably simpler.

- an MDNode is designated as function-local when created, and continues to be even if its operands are modified not to refer to function-local IR
- function-localness is designated via lowest bit in SubclassData
- getLocalFunction() descends MDNode tree to see if it is consistently function-local
Add verification of MDNodes to checks that MDNodes are consistently function-local.
Update AsmWriter to use isFunctionLocal().

In getMallocArraySize(), fix bug in the case that array size is the product of 2 constants.
Extend isArrayMalloc() and getMallocArraySize() to handle case where malloc is used as char array.
Ensure that ArraySize in LowerAllocations::runOnBasicBlock() is correct type.
Extend Instruction::isSafeToSpeculativelyExecute() to handle malloc calls.
Add verification for malloc calls.

Assert1(isa<>); cast<> is not safe as Assert1 does not terminate the program.

In NDEBUG builds location info and the message is off (it only prints

To support this, add some utility functions to Type to help support
vector/scalar-independent code. Change ConstantInt::get and

ConstantInt::get that uses a static IntegerType type, for
