Some of these maps may merge in the future, but for now it's convenient to have
a utility function for them.

memoize the results. This improves compile time in code which highly complex
expressions which get queried many times.

Introduce option -Wargument-larger-than[=N] which warns about function definitions if they take by-value
or return by-value any POD that is larger than some threshold (default is 64 bytes).

Implements rdar://8548050.

They are replaced with calls to the CoreFoundation function 
CFStringCreateWithBytes() by a portion of the IRForTarget pass.

Now that the MBlaze backend is in its own directory, split the test cases into multiple files for different types of instructions.

Would be good for a Linux person to review this.

Objective-C message sends, which have only whitespace in their
TypedText chunk. Such results have no purpose.

In EvalArguments allow for evaluation of first argument always as a lvalue. Will be used for CXXOperatorCallExpr that represents method call.

This completes the fixes for Radar 8673120.

It is generally not sufficient to check if the starting offset is in range
of the maximum offset that can be efficiently used for the target.

This makes it more clear that the symbol is an internal, compiler-generated
name and gives a little more description about its contents.

It was mistakenly looking at the pointer type when checking for the size of
global variables.  This is a partial fix for Radar 8673120.

Avoid isel movcc of large immediates when the large immediate is available in a register. These immediates aren't free.

needs to be checked that this won't break LCSSA form.
Change the existing checking method to a more direct one:
rather than seeing if all predecessors belong to the loop,
check that the replacing value is either not in any loop or
is in a loop that contains the phi node.
