[Hexagon] Removing old newvalue store variants.  Adding postincrement immediate newvalue stores.

[Hexagon] Adding postincrement register newvalue stores.

DebugInfo: Omit is_stmt from line table entries on the same line.

GCC does this for non-zero discriminators and since GCC doesn't produce
column info, that was the only place it comes up there. For LLVM, since
we can emit discriminators and/or column info, it makes more sense to
invert the condition and just test for changes in line number.

This should resolve at least some of the GDB 7.5 test suite failures
created by recent Clang changes that increase the location fidelity
(which, since Clang defaults to including column info on Linux by
default created a bunch of cases that confused GDB).

In theory we could do this better/differently by grouping actual source
statements together in a similar manner to the way lexical scopes are
handled but given that GDB isn't really in a position to consume that (&
users are probably somewhat used to different lines being different
'statements') this seems the safest and cheapest change. (I'm concerned
that doing this 'right' would bloat the debugloc data even further -
something Duncan's working hard to address)

RTDyldMemoryManager.cpp: Make the reference to __morestack weak.

This fixes the DSO build for now. Eventually we should develop some
other mechanism to make this work correctly with DSOs.
