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.

Move the extern symbol declarations outside of

DynamicLibrary::SearchForAddressOfSymbol and force them to have "C"
linkage.
Interestingly, GCC treats the block-scoped "extern" declarations we
previously had as if they were extern "C" declarations (or, at least,
were in the global namespace), so that GCC bug papered over this LLVM
bug. Clang and EDG get the linkage correct; this new variant seems to
work for both GCC and Clang.

Fix the Convert to scalar to not insert dead loads in the store case. The
...
load is needed when we have a small store into a large alloca (at which
point we get a load/insert/store sequence), but when you do a full-sized
store, this load ends up being dead.
This dead load is bad in really large nasty testcases where the load ends
up causing mem2reg to insert large chains of dependent phi nodes which only
ADCE can delete. Instead of doing this, just don't insert the dead load.

To make things interesting, I added MORE code to set the ordering of
...
SDNodes. This time in the load/store and limited-precision code.

Changed slot index ranges for MachineBasicBlocks to be exclusive of endpoint.
...
This fixes an in-place update bug where code inserted at the end of basic blocks may not be covered by existing intervals which were live across the entire block. It is also consistent with the way ranges are specified for live intervals.

assign the ordering when called. Combine some of the ordering assignments to
keep things simple.

Add a fastpath to Load GVN to special case when we have exactly one dominating
...
load to avoid even messing around with SSAUpdate at all. In this case (which
is very common, we can just use the input value directly).
This speeds up GVN time on gcc.c-torture/20001226-1.c from 36.4s to 16.3s,
which still isn't great, but substantially better and this is a simple speedup
that applies to lots of different cases.

Remove special-case SROA optimization of variable indexes to one-element and

two-element arrays. After restructuring the SROA code, it was not safe to
do this without adding more checking. It is not clear that this special-case
has really been useful, and removing this simplifies the code quite a bit.
