Changes in directory llvm/lib/Transforms/Instrumentation/ProfilePaths:
EdgeCode.cpp updated: 1.30 -> 1.31
InstLoops.cpp updated: 1.21 -> 1.22
ProfilePaths.cpp updated: 1.43 -> 1.44

Log message:
When a function takes a variable number of pointer arguments, with a zero
pointer marking the end of the list, the zero *must* be cast to the pointer
type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.
The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.
