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

Give ParseInstructionMetadata access to the PerFunctionState object.
This is in preparation for generalizing its parsing of function-local
values.

Simplify this code. NamedMDNode operands are MDNodes.

Fix the opcode and the operands for the load instruction.

Add register class hack that needs to go away, but makes it more obvious
that it needs to go away.  Use loadRegFromStackSlot where possible.

Also, remember to update the value map.

fix rdar://7997827 - Accept and ignore LL and ULL suffixes on integer literals.

Also fix 0b010 syntax to actually work while we're at it :-)

Add some more debugging code, make it more obvious that RegOffset is
getting an address for an object and select some default values.

Don't need the extra register here.

llvmc: Make syntax more consistent.

CompilationGraph and LanguageMap definitions do not use special syntax anymore.

Add some more "get address into register" code and a more TODOs/FIXMEs.

Verify that a non-uniqued non-temporary MDNode is not deleted via
MDNode::deleteTemporary.

Remove the MFI storage of the local allocation block size. It's not needed.

ELFObjectWriter: Run ComputeSymbolTable before recording relocations. This way we can use the information it has computed and don't have to recompute the same stuff over and over again.

Better handling of local offsets for downwards growing stacks. This corrects
relative offsets when there are offsets encoded in the instructions and
simplifies final allocation in PEI. rdar://8277890
