432a205769 Let the inliner update the callgraph to reflect the changes it makes, instead 
of doing it ourselves.  This fixes Transforms/Inline/2006-01-14-CallGraphUpdate.ll

468fb1df7d Teach the inliner to update the CallGraph itself, and have it add edges to 
llvm.stacksave/restore when it inserts calls to them.

ccca3ca85f Permit inlining functions that contain dynamic allocations now that 
InlineFunction handles this case safely.  This implements
Transforms/Inline/dynamic_alloca_test.ll.

bf229f488a If inlining a call to a function that contains dynamic allocas, wrap the

1fdf4a859f Use ClonedCodeInfo to avoid another walk over the inlined code, this this 
time in common C cases.

727d1dd587 Use the ClonedCodeInfo object to avoid scans of the inlined code when 
it doesn't contain any calls.  This is a fairly common case for C++ code,
so it will probably speed up the inliner marginally in these cases.

21f20558d6 Fix a bug I noticed by inspection: if the first instruction in the inlined 
function was not an alloca, we wouldn't check the entry block for any allocas,
leading to increased stack space in some cases.  In practice, allocas are almost
always at the top of the block, so this was never noticed.

a243db8c41 Fix calls that need to store values in stack slots, to not copy the stack 
pointer.  This allows us to emit stuff like this:

        li r10, 0

        or r3, r10, r10
        or r4, r10, r10

        or r8, r10, r10
        or r9, r10, r10
        bl L_bar$stub

instead of this:

        or r2, r1, r1     ;; Extraneous copy.
        li r10, 0
        stw r10, 56(r2)
        or r3, r10, r10
        or r4, r10, r10
        or r5, r10, r10

3159048c00 Patch #9 from Saem: 
"Cut up the runPasses method into smaller pieces.  The small private
helpers should  be easier to deal with when code shuffling arising
from creating the new specialised batchers, not to mention, they're
much easier to understand.

I inlined them, in case function call overhead would be noticeable --
doubtful."
