aeb8abb0e0 Revert r112091, "Remap metadata attached to instructions when remapping 
individual ...", which depends on r111922, which I am reverting.

instructions, not when remapping modules.

30fd721e48 Use MapValue in the Linker instead of having a private function 
which does the same thing. This eliminates redundant code and
handles MDNodes better. MDNode linking still doesn't fully
work yet though.

5cbd5888e7 MapValue support for MDNodes. This is similar to r109117, except 
that it avoids a lot of unnecessary cloning by avoiding remapping
MDNode cycles when none of the nodes in the cycle actually need to
be remapped. Also it uses the new temporary MDNode mechanism.

7094bd27bc Whether function-local or not, a MDNode may reference a Function in which case 
it needs to be mapped to refer to the function in the new module, not the old
one. Fixes PR7700.

a24bf5907c If a metadata operand is seeded in value map and the metadata should also be seeded in value map. This is not limited to function local metadata. 
Failure to seed metdata in such cases causes troubles when in a cloned module, metadata from a new module refers to values in old module. Usually this results in mysterious bugpoint crashes. For example,

642049e127 It turns out that this #include is needed because otherwise 
ValueMapper.cpp ends up calling an out of line 
__ZNK4llvm12PATypeHolder3getEv, which is a template and llvm-config
determines arbitrarily to use the one in libipo.  This sucks, but
keeping the #include is a reasonable workaround.

f955a6ef49 llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

ae8a3ff177 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

Running the inliner on 252.eon used to take 48.4763s, now it takes 14.4148s.
