fixupLineNumbers - Update inlined instructions' line numbers to to encode location where these instructions are inlined.

HandleByValArgument - When inlining a call site that has a byval argument, we have to make the implicit memcpy explicit by adding it.

static bool HandleCallsInBlockInlinedThroughInvoke	(	BasicBlock *	BB,
		InvokeInliningInfo &	Invoke
	)

static

HandleCallsInBlockInlinedThroughInvoke - When we inline a basic block into an invoke, we have to turn all of the calls that can throw into invokes. This function analyze BB to see if there are any calls, and if so, it rewrites them to be invokes that jump to InvokeDest and fills in the PHI nodes in that block with the values specified in InvokeDestPHIValues.

Returns true to indicate that the next block should be skipped.

static void HandleInlinedInvoke	(	InvokeInst *	II,
		BasicBlock *	FirstNewBlock,
		ClonedCodeInfo &	InlinedCodeInfo
	)

static

HandleInlinedInvoke - If we inlined an invoke site, we need to convert calls in the body of the inlined function into invokes.

II is the invoke instruction being inlined. FirstNewBlock is the first block of the inlined code (the last block is the end of the function), and InlineCodeInfo is information about the code that got inlined.

UpdateCallGraphAfterInlining - Once we have cloned code over from a callee into the caller, update the specified callgraph to reflect the changes we made. Note that it's possible that not all code was copied over, so only some edges of the callgraph may remain.
