Rename some VLD1/VST1 instructions to match the implementation, i.e., the
corresponding NEON instructions, instead of operation they are currently

Refactor instruction encoding arguments for VLDnLN/VSTnLN classes to

we can reapply the InvokeInst operand reordering patch. (see r98957).

Free all Constants in ~LLVMConstantImpl.  We avoid assertion failures
by dropping all references from all constants that can use other
constants before trying to destroy any of them.

I also had to free bugpoint's Module in ~BugDriver().

Re-add the Metadata.h include to LLVMContextImpl.h so that MDNode is complete
