e90da97f3e LHS = X86ISD::CMOVcc LHS, RHS means LHS = RHS if cc. So the operands must be 
flipped around.

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

f0638c5f71 New testcase that functions with dynamic allocas can be inlined, and are 
inlined correctly.

bf229f488a If inlining a call to a function that contains dynamic allocas, wrap the 
resultant code with llvm.stacksave/llvm.stackrestore intrinsics.

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.
