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

InlineFunction handles this case safely.  This implements
Transforms/Inline/dynamic_alloca_test.ll.

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.
