Duncan Sands 89d412a140 Fix PR8494: when reading invalid bitcode, getTypeByID may return 
a null pointer.

Bill Wendling 0198ce06fc Provide a fast "get me the target triple from the module" API. This can 
drastically reduce the linking time during LTO.

Patch by Shantonu Sen!

Dale Johannesen baa5d045c9 Add X86 MMX type to bitcode and Type. 
(The Ada bindings probably need it too, but all the
obvious places to change say "do not edit this file".)

Bill Wendling e26fffc597 Auto-upgrade the magic ".llvm.eh.catch.all.value" global to 
"llvm.eh.catch.all.value". Only the name needs to be changed.

Dan Gohman 6dbbab6895 Discard metadata produced by LLVM 2.7. The value enumeration it used 
is different from what the code now uses in a two ways: NamedMDNodes
were considered Values and included in the numbering, and the
function-local metadata counter wasn't reset between functions.

The later problem breaks lazy deserialization, so instead of trying
to emulate the old numbering, just drop the old metadata. The only
in-tree use case is debug info with LTO, where the QOI loss is
considered acceptable.

Dan Gohman 26d837d086 Fix the bitcode reader to clear out function-specific state 
from MDValueList between each function, now that the bitcode
writer is reusing the index space for function-local metadata.

Dan Gohman ab09a12cad When we know we have an MDValue or MDString, call EnumerateMetadata 
directly instead of going through EnumerateValue.

Bill Wendling 578ee4070c Create the new linker type "linker_private_weak_def_auto". 
It's similar to "linker_private_weak", but it's known that the address of the
object is not taken. For instance, functions that had an inline definition, but
the compiler decided not to inline it. Note, unlike linker_private and
linker_private_weak, linker_private_weak_def_auto may have only default
visibility.  The symbols are removed by the linker from the final linked image
(executable or dynamic library).

Dan Gohman 16a5d98c3a Introduce a new temporary MDNode concept. Temporary MDNodes are 
not part of the IR, are not uniqued, and may be safely RAUW'd.
This replaces a variety of alternate mechanisms for achieving
the same effect.
