3b08c33f33 Remove dead debug info intrinsics. 
Intrinsic::dbg_stoppoint
 Intrinsic::dbg_region_start 
 Intrinsic::dbg_region_end 
 Intrinsic::dbg_func_start
AutoUpgrade simply ignores these intrinsics now.

ecba817b0e fix Analysis/DebugInfo.h to not include Metadata.h. Do this 
by moving one method out of line and eliminating redundant checks
from other methods.

c12382b7c8 rename "elements" of metadata to "operands". "Elements" are 
things that occur in types.  "operands" are things that occur
in values.

9afb6e9c27 Optimize MDNode to coallocate the operand list immediately 
after the MDNode in memory.  This eliminates the operands
pointer and saves a new[] per node.

Note that the code in DIDerivedType::replaceAllUsesWith is wrong
and quite scary.  A MDNode should not be RAUW'd with something
else: this changes all uses of the mdnode, which may not be debug
info related!  Debug info should use something non-mdnode for
declarations.

84e9de4a58 Final step in the metadata API restructuring: move the 
getMDKindID/getMDKindNames methods to LLVMContext (and add
convenience methods to Module), eliminating MetadataContext.
Move the state that it maintains out to LLVMContext.

9ec640a902 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.

cd3aa9d1ff rename getMDKind -> getMDKindID, make it autoinsert if an MD Kind 
doesn't exist already, eliminate registerMDKind.  Tidy up a bunch
of random stuff.

cd79ebb23c The phi translated pointer can be computed when returning a partially cached result 
instead of stored.  This reduces memdep memory usage, and also eliminates a bunch of
weakvh's.  This speeds up gvn on gcc.c-torture/20001226-1.c from 23.9s to 8.45s (2.8x)
on a different machine than earlier.

07f0e8ec8a fix an overly conservative caching issue that caused memdep to 
cache a pointer as being unavailable due to phi trans in the
wrong place.  This would cause later queries to fail even when
they didn't involve phi trans.
