c4fbd3fd62 X86 intrinsics moved form X86ISelLowering.cpp to X86IntrinsicsInfo.h
X86ISelLowering.cpp has a long switch for intrinsics. I moved a part of
this long switch to the new intrinsics table in X86IntrinsicsInfo.h.
No functional changes, just code and compile time optimization.

8ecb7e2243 IR: Revert r223618 behaviour of MDNode::concatenate()
r223618 including special handling of `MDNode::intersect()`: if the
first operand is a self-reference with the same operands you're trying
to return, return it instead.

Reuse that handling in `MDNode::concatenate()` in the hopes that it
fixes a polly test that seems to rely on the old behaviour [1].

7280d8ccce IR: Drop uniquing for self-referencing MDNodes
It doesn't make sense to unique self-referencing nodes.  Drop uniquing
for them.

Note that `MDNode::intersect()` occasionally returns self-referencing
nodes.  Previously these would be returned by `MDNode::get()`.  I'm not
convinced this was intended behaviour -- to me it seems it should return
a node whose only operand is the self-reference -- but I don't know much
about alias scopes so I'm preserving it for now.

This is part of PR21532.

6bb158dd34 IR: Remove reference to ENABLE_MDNODE_UNIQUING
Apparently `MDNode` uniquing used to be optional.  I suppose the
configure flag must have disappeared at some point.  Change the test so
it actually tests uniquing, and remove the check for
`ENABLE_MDNODE_UNIQUING`.

a77df65a84 IR: Add missing tests for function-local metadata
Add assembly and bitcode tests that I neglected to add in r223564 (IR:
Disallow complicated function-local metadata) and r223574 (IR: Disallow
function-local metadata attachments).

Found a couple of bugs:

  - The error message for function-local attachments gave the wrong line
    number -- it indicated the next token (typically on the next line)
    instead of the token that started the attachment.  Fixed.

  - Metadata arguments of the form `!{i32 0, i32 %v}` (or with the
    arguments reversed) fired an assertion in `ValueEnumerator` in LLVM
    v3.5, so I suppose this never really worked.  I suppose this was
    "fixed" by r223564.

(Thanks to dblaikie for pointing out my omission.)

2cd5836249 Make the DenseMap bucket type configurable and use a smaller bucket for DenseSet.
DenseSet used to be implemented as DenseMap<Key, char>, which usually doubled
the memory footprint of the map. Now we use a compressed set so the second
element uses no memory at all. This required some surgery on DenseMap as
all accesses to the bucket now have to go through methods; this should
have no impact on the behavior of DenseMap though. The new default bucket
type for DenseMap is a slightly extended std::pair as we expose it through
DenseMap's iterator and don't want to break any existing users.

a421ac689f SelectionDAG switch lowering: Replace unreachable default with most popular case.
This can significantly reduce the size of the switch, allowing for more
efficient lowering.

I also worked with the idea of exploiting unreachable defaults by
omitting the range check for jump tables, but always ended up with a
non-neglible binary size increase. It might be worth looking into some more.

SimplifyCFG currently does this transformation, but I'm working towards changing
that so we can optimize harder based on unreachable defaults.
