72115d5fb6 Add to the split module utility an SCC based method which allows not to globalize any local variables. 
Summary:
    Currently llvm::SplitModule as the first step globalizes all local objects, which might not be desirable in some scenarios.
    This change adds a new flag to llvm::SplitModule that uses SCC approach to search for a balanced partition without the need to externalize symbols.
    Such partition might not be possible or fully balanced for a given number of partitions, and is a function of the module properties (global/local dependencies within the module).

4c1241282f [X86][AVX2] Broadcast subvectors 
AVX2 can only broadcast from the zero'th element of a vector, but if the broadcastable element is the zero'th element of a 128-bit subvector its advantageous to extract the subvector, broadcast from that and avoid the loading of shuffle mask data that would be needed for VPERMPS/VPERMD. The only exception being when the source type is 4f64 or 4i64 which can directly use the immediate shuffle VPERMPD/VPERMQ directly.

a09c2fcc35 TargetLowering: Improve handling of (setcc ([sz]ext x) 0, cc) in SimplifySetCC 
Summary:
When SimplifySetCC sees a setcc node that compares the result of a
value extension operation with a constant, it tries to simplify the
setcc node by eliminating the extension and shrinking the constant.

If shrinking the inputs to setcc is deemed not desirable by the target
(e.g. the target does not want a setcc comparing i1 values), then it
is still possible to optimize this sequence in some cases.

This patch adds the following combines to SimplifySetCC when shrinking setcc
inputs is not desirable:

(setcc ([sz]ext (setcc x, y, cc)), 0, setne) -> (setcc (x, y, cc))
(setcc ([sz]ext (setcc x, y, cc)), 0, seteq) -> (setcc (x, Y, !cc))

There are no tests for this yet, but once AMDGPU correctly implements
TargetLowering::isTypeDesirableForOp(), this new combine will be
exercised by the existing CodeGen/AMDGPU/setcc-opt.ll test.

c96132f0d0 [Orc] Enable ORC execution unit tests on non-windows platforms. 
Previously these were Darwin-only. Since the switch to direct binary emission
of stubs, trampolines and resolver blocks, these should work on other *nix
platforms too.

These tests can be enabled on Windows once known issues with ORC's handling of
Windows symbol mangling (see e.g. https://llvm.org/PR25940) have been fixed.

aa011535f3 [IndVars] Fix PR25576 
`LCSSASafePhiForRAUW` as computed was incorrect -- in cases like
these (this exact example does not actually trigger the bug):

define i32 @f(i32 %n, i1* %c) {
entry:
  br label %outer.loop

outer.loop:
  br label %inner.loop

inner.loop:
  %iv = phi i32 [ 0, %outer.loop ], [ %iv.inc, %inner.loop ]
  %iv.inc = add nuw nsw i32 %iv, 1
  %tc = udiv i32 %n, 13
  %be.cond = icmp ult i32 %iv, %tc
  br i1 %be.cond, label %inner.loop, label %inner.exit

inner.exit:
  %iv.lcssa = phi i32 [ %iv, %inner.loop ]
  %outer.be.cond = load volatile i1, i1* %c
  br i1 %outer.be.cond, label %outer.loop, label %leave

leave:
  %iv.lcssa.lcssa = phi i32 [ %iv.lcssa, %inner.exit ]
  ret i32 %iv.lcssa.lcssa
}

`LCSSASafePhiForRAUW` is true for `%iv.lcssa` when re-rewriting the exit
value of `%iv` for `%inner.loop` to `%tc` (this can happen due to
`SCEVExpander::findExistingExpansion`), but the RAUW breaks LCSSA.

To fix this, instead of computing `SafePhi` with special logic, decide
the safety of RAUW directly via `replacementPreservesLCSSAForm`.
