Avoid going through the LLVMContext for type equality where it's safe to dereference the type pointer.

rename "elements" of metadata to "operands". "Elements" are
things that occur in types. "operands" are things that occur
in values.

This is a major cleanup of the instruction metadata interfaces that
I asked Devang to do back on Sep 27. Instead of going through the
MetadataContext class with methods like getMD() and getMDs(), just
ask the instruction directly for its metadata with getMetadata()
and getAllMetadata().

This includes a variety of other fixes and improvements: previously
all Value*'s were bloated because the HasMetadata bit was thrown into
value, adding a 9th bit to a byte. Now this is properly sunk down to
the Instruction class (the only place where it makes sense) and it
will be folded away somewhere soon.

This also fixes some confusion in getMDs and its clients about
whether the returned list is indexed by the MDID or densely packed.
This is now returned sorted and densely packed and the comments make
this clear.

This introduces a number of fixme's which I'll follow up on.

change the strange MetadataContext::getMDs function to expose less
irrelevant internal implementation details to clients.

eliminate the elem_* iterator stuff from NamedMDNode.

Revert 85678/85680. The decision is to stay with the current form of
indirectbr, thus we don't need "blockaddr(@func, null)". Eliminate it
for simplicity.

Make blockaddress(@func, null) be valid, and make 'deleting a basic
block with a blockaddress still referring to it' replace the invalid
blockaddress with a new blockaddress(@func, null) instead of

Make blockaddress(@func, null) be valid, and make 'deleting a basic
block with a blockaddress still referring to it' replace the invalid
blockaddress with a new blockaddress(@func, null) instead of a
inttoptr(1).

This changes the bitcode encoding format, and still needs codegen
support (this should produce a non-zero value, referring to the entry
block of the function would also be quite reasonable).

Rename MDNode.h header. It defines MDnode and other metadata classes.
New name is Metadata.h.
