instead of InlineFunction.

a2fbc0ae1b Finally land the InvokeInst operand reordering. 
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.

dcddd5701c Don't back past debug info intrinsics; SCEVExpander's strategy 
for ignoring debug info intrinsics everywhere else is to advance
past them, and it needs to be consistent.

7a743e15e3 Now that hopefully all direct accesses to InvokeInst operands are fixed 
we can reapply the InvokeInst operand reordering patch. (see r98957).

89d4e3c3fd Fix more places to more thoroughly ignore debug intrinsics. This fixes 
use-before-def errors in SCEVExpander-produced code in sqlite3 when debug
info with optimization is enabled, though the testcases for this are
dependent on use-list order.

8335f9c0bf Recommit r80858 again (which has been backed out in r80871). 
This time I did a self-hosted bootstrap on Linux x86-64,
with no problems. Let's see how darwin 64-bit self-hosting
goes. At the first sign of failure I'll back this out.

Maybe the valgrind bots give me a hint of what may be wrong
(it at all).

6556c8962c Add the ability to "intern" FoldingSetNodeID data into a 
BumpPtrAllocator-allocated region to allow it to be stored in a more
compact form and to avoid the need for a non-trivial destructor call.

Use this new mechanism in ScalarEvolution instead of
FastFoldingSetNode to avoid leaking memory in the case where a
FoldingSetNodeID uses heap storage, and to reduce overall memory
usage.

5c9b0e1a6e Change SCEVNAryExpr's operand array from a SmallVector to a plain 
pointer and length, and allocate the arrays in ScalarEvolution's
BumpPtrAllocator, so that they get released when their owning
SCEV gets released. SCEVs are immutable, so they don't need to worry
about operand array resizing. This fixes a memory leak reported
in PR6637.

b495cad7ca Try to keep the cached inliner costs around for a bit longer for big functions. 
The Caller cost info would be reset everytime a callee was inlined. If the
caller has lots of calls and there is some mutual recursion going on, the
caller cost info could be calculated many times.

This patch reduces inliner runtime from 240s to 0.5s for a function with 20000
small function calls.

This is a more conservative version of r98089 that doesn't break the clang
test CodeGenCXX/temp-order.cpp. That test relies on rather extreme inlining
for constant folding.
