Will Dietz b50565b21a [ubsan] Drop use of __atomic_exchange_n for now to fix build for some. 
Need a more reliable way to check for support of this intrinsic.

Nadav Rotem 977e0be4a0 Efficient lowering of vector sdiv when the divisor is a splatted power of two constant. 
PR 14848. The lowered sequence is based on the existing sequence the target-independent
DAG Combiner creates for the scalar case.

Patch by Zvi Rackover.

Nico Weber 69dce49c76 Don't mention -fno-diagnostics-print-source-range-info in manual. 
Clang doesn't understand it.

If someone wants to teach clang about that flag instead, please also add
support for -fno-diagnostics-parseable-fixits for consistency.

Until then, let the documentation match the current behavior.

Andrew Trick 9f0b95f260 MIsched: add an ILP window property to machine model. 
This was an experimental option, but needs to be defined
per-target. e.g. PPC A2 needs to aggressively hide latency.

I converted some in-order scheduling tests to A2. Hal is working on
more test cases.

Jim Ingham 196bbc2571 Add a "--reverse" or "-r" option to the "list" with no options command. This will list backwards from the 
last source point listed.
Also fix the setting of the default file & line to the file containing main, when you do a plain "list".

Sean Silva 0657b40b3c Inline this into its only caller. 
It's clearer and additionally this gets rid of the usage of `DefmID`,
which doesn't really correspond to anything in the language (it was just
used in the name of this parsing function which parsed a `MultiClassID`
and returned that multiclass's record).

This area of the code still needs a lot of work.

Sean Silva c95fe2804d docs: Bring TableGen syntax a bit closer to reality.

Nick Kledzik cc3d2dca60 Better tie together ContentType and Permissions. 
Since most content types (e.g. typeCode) have a 
preferred Permission, add a function to do that mapping.
Then hook up to YAML Reader and Writer such that
the 'permissions:' key does not need to be specified unless
overriding what the content type prefers.

Douglas Gregor 3552dabfe1 When name lookup for a redeclaration finds declarations that are known 
(because they are part of some module) but have not been made visible
(because they are in a submodule that wasn't imported), filter out
those declarations unless both the old declaration and the new
declaration have external linkage. When one or both has internal
linkage, there should be no conflict unless both are imported.

Eli Bendersky 5277120dd0 Simplify the code a bit: MCRelaxableFragment doesn't need a separate getInstSize 
method because getContents().size() already covers it. So computeFragmentSize
can use the generic MCEncodedFragment interface when querying both Data and
Relaxable fragments for contents sizes.

No change in functionality
