fa1211f69b Enable first-class aggregates support. 
Remove the GetResultInst instruction. It is still accepted in LLVM assembly
and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove
support for return instructions with multiple values. These are auto-upgraded
to use InsertValueInst instructions.

The IRBuilder still accepts multiple-value returns, and auto-upgrades them
to InsertValueInst instructions.

0c71732497 Use a CallSite to find the nth argument of a call/invoke instruction instead of 
using getOperand() directly. This makes things work with invoke instructions as
well.

fd17357643 Reapply r52397 (make IPConstProp promote returned arguments), but fixed this 
time. Sorry for the trouble!

This time, also add a testcase, which I should have done in the first place...

332836d68d Learn IPConstProp to propagate arguments that are directly returned. Strictly 
speaking these are not constant values. However, when a function always returns
one of its arguments, then from the point of view of each caller the return
value is constant (or at least a known value) and can be replaced.

f03c1ae407 Learn IPConstProp to look at individual return values and propagate them 
individually.

Also learn IPConstProp how returning first class aggregates work, in addition
to old style multiple return instructions.

Modify the return-constants testscase to confirm this behaviour.

e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to 
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

af555adc15 If a function always returns a constant, replace all calls sites with that 
constant value.  This makes the return value dead and allows for
simplification in the caller.

This implements IPConstantProp/return-constant.ll

This triggers several dozen times throughout SPEC.

0d3773d8b1 Do not let dead constant expressions hanging off of functions prevent IPCP. 
This allows to elimination of a bunch of global pool descriptor args from
programs being pool allocated (and is also generally useful!)

4f2cf030e8 'Pass' should now not be derived from by clients. Instead, they should derive 
from ModulePass.  Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.
