Consolidate the code which handles string table offsets less than 999999
with the code for offsets less than 9999999. While we are here,
simplify the code by not using sprintf to generate the string.

Use existing functionality provided in changeToUnreachable instead of
reinventing it in LoopSimplify.
No functionality change is intended.

Changes in X86.td:
I set features of Intel processors in incremental form: IVB = SNB + X HSW = IVB + X ..
I added Skylake client processor and defined it's features
FeatureADX was missing on KNL
Added some new features to appropriate processors SMAP, IFMA, PREFETCHWT1, VMFUNC and others

SCCP has code identical to changeToUnreachable's behavior, switch it
over to just call changeToUnreachable.
No functionality change intended.

InstCombine and SCCP both want to remove dead code in a very particular
way but using identical means to do so. Share the code between the two.
No functionality change is intended.

A cleanup can have paths which unwind or end up in unreachable.
If there is an unreachable path *and* a path which unwinds to caller,
we would mistakenly inject an unwind path to a catchswitch on the
unreachable path. This results in a verifier assertion firing because
the cleanup unwinds to two different places: to the caller and to the
catchswitch.
This occured because we used getCleanupRetUnwindDest to determine if the
cleanuppad had no cleanuprets.
This is incorrect, getCleanupRetUnwindDest returns null for cleanuprets
which unwind to caller.

Generalised mask generation / subvector extraction to use the input/output types directly instead of an if/else through all the currently accepted types.

Summary: Helper so we don't have to enumerate nvptx && nvptx64 everywhere.

Summary:
Previously, we would just output "foo = bar" in the assembly, and then
ptxas would choke. Now we die before emitting any invalid code.

Summary:
Update ObjectTransformLayer::addObjectSet to take the object set by
value rather than reference and pass it to the base layer with move
semantics rather than copy, to match r258185's changes to
ObjectLinkingLayer.
Update the unit test to verify that ObjectTransformLayer's signature stays
in sync with ObjectLinkingLayer's.

For the moment, this file takes way too long to run (see inline comments), but
that should be a temporary problem. The fact that the compile time is so slow
for a target that doesn't support maskmov may be a bug worth investigating too.

target is macho.
It looks like the check for macho was accidentally dropped in r132959.
I don't have a test case, but I'll add one if anyone knows how this can
be tested.

If the INSERTPS zeroes out all the referenced elements from either of the 2 input vectors (and the input is not already UNDEF), then set that input to UNDEF to reduce dependencies.

Some of the conditions necessary to produce ccmp sequences were only
checked in recursive calls to emitConjunctionDisjunctionTree() after
some of the earlier expressions were already built. Move all checks over
to isConjunctionDisjunctionTree() so they are all checked before we
start emitting instructions.
Also rename some variable to better reflect their usage.
