6cb8c23db1 Reapply r112091 and r111922, support for metadata linking, with a 
fix: add a flag to MapValue and friends which indicates whether
any module-level mappings are being made. In the common case of
inlining, no module-level mappings are needed, so MapValue doesn't
need to examine non-function-local metadata, which can be very
expensive in the case of a large module with really deep metadata
(e.g. a large C++ program compiled with -g).

This flag is a little awkward; perhaps eventually it can be moved
into the ClonedCodeInfo class.

The ValueMapper used by various cloning utility maps MDNodes also.

0ca2f28458 rename InlineInfo.DevirtualizedCalls -> InlinedCalls to 
reflect that it includes all inlined calls now, not just
devirtualized ones.

076863225c switch InlineInfo.DevirtualizedCalls's list to be of WeakVH. 
This fixes a bug where calls inlined into an invoke would get
changed into an invoke but the array would keep pointing to
the (now dead) call.  The improved inliner behavior is still
disabled for now.

fe9af3b1f7 The inliner was choosing to not consider call sites 
that appear in the SCC as a result of inlining as candidates
for inlining.  Change this so that it *does* consider call 
sites that change from being indirect to being direct as a
result of inlining.  This allows it to completely 
"devirtualize" the testcase.

60915146f4 refactor the interface to InlineFunction so that most of the in/out 
arguments are handled with a new InlineFunctionInfo class.  This 
makes it easier to extend InlineFunction to return more info in the
future.

c8d76d5afb Make Loop and MachineLoop be subclasses of LoopBase, rather than typedefs, 
using the Curiously Recurring Template Pattern with LoopBase.

This will help further refactoring, and future functionality for
Loop. Also, Headers can now foward-declare Loop, instead of pulling
in LoopInfo.h or doing tricks.

8b477ed579 Add a pointer to the owning LLVMContext to Module. This requires threading LLVMContext through a lot 
of the bitcode reader and ASM parser APIs, as well as supporting it in all of the tools.

Patches for Clang and LLVM-GCC to follow.
