Chris Bieneman bef847c3ae [Lanai] Rename LanaiInstPrinter library to LanaiAsmPrinter
Summary:
    This is in keeping with LLVM convention. The classes are InstPrinters, but the library is ${target}AsmPrinter.

This patch is in response to bryant pointing out to me that Lanai was the only backend deviating from convention here. Thanks!

Sanjay Patel 562272536a [InstSimplify] try to eliminate icmp Pred (add nsw X, C1), C2
I was surprised to see that we're missing icmp folds based on 'add nsw' in InstCombine, 
but we should handle the InstSimplify cases first because that could make the InstCombine
code simpler.

Here are Alive-based proofs for the logic:

Name: add_neg_constant
Pre: C1 < 0 && (C2 > ((1<<(width(C1)-1)) + C1))
%a = add nsw i7 %x, C1
%b = icmp sgt %a, C2
  =>
%b = false

Name: add_pos_constant
Pre: C1 > 0 && (C2 < ((1<<(width(C1)-1)) + C1 - 1))
%a = add nsw i6 %x, C1
%b = icmp slt %a, C2
  =>
%b = false

Name: nuw
Pre: C1 u>= C2
%a = add nuw i11 %x, C1
%b = icmp ult %a, C2
  =>
%b = false

Geoff Berry 92a286ae5a [SelectionDAG] Handle inverted conditions when splitting into multiple branches.
Summary:
When conditional branches with complex conditions are split into
multiple branches in SelectionDAGBuilder::FindMergedConditions, also
handle inverted conditions.  These may sometimes appear without having
been optimized by InstCombine when CodeGenPrepare decides to sink and
duplicate cmp instructions, causing them to have only one use.  This
problem can be increased by e.g. GVNHoist hiding more cmps from
InstCombine by combining equivalent cmps from different blocks.

For example codegen X & !(Y | Z) as:
    jmp_if_X TmpBB
    jmp FBB
  TmpBB:
    jmp_if_notY Tmp2BB
    jmp FBB
  Tmp2BB:
    jmp_if_notZ TBB
    jmp FBB

Chandler Carruth 6acdca78a0 [PH] Replace uses of AssertingVH from members of analysis results with
a lazy-asserting PoisoningVH.

AssertVH is fundamentally incompatible with cache-invalidation of
analysis results. The invaliadtion happens after the AssertingVH has
already fired. Instead, use a PoisoningVH that will assert if the
dangling handle is ever used rather than merely be assigned or
destroyed.

This patch also removes all of the (numerous) doomed attempts to work
around this fundamental incompatibility. It is a pretty significant
simplification IMO.

The most interesting change is in the Inliner where we still do some
clearing because we don't want to rely on the coarse grained
invalidation strategy of the containing pass manager. However, I prefer
the approach that contains this logic to the cleanup phase of the
Inliner, and I think we could enhance the CGSCC analysis management
layer to make this even better in the future if desired.

The rest is straight cleanup.

I've also added a test for one of the harder cases to work around: when
a *module analysis* contains many AssertingVHes pointing at functions.

Chandler Carruth 942c31474f [PM] Introduce a PoisoningVH as a (more expensive) alternative to
AssertingVH that delays any reported error until the handle is *used*.

This allows data structures to contain handles which become dangling
provided the data structure is cleaned up afterward rather than used for
anything interesting.

The implementation is moderately horrible in part because it works to
leave AssertingVH in place, undisturbed. If at some point there is
consensus that this is simply how AssertingVH should be used, it can be
substantially simplified.

This remains a boring pointer in a non-asserts build as you would
expect. The only place we pay cost is in asserts builds.

I plan to use this as a basis for replacing the asserting VHs that
currently dangle in the new PM until invalidation occurs in both LVI and
SCEV.

Greg Parker ed0a95cbec [lit] Allow boolean expressions in REQUIRES and XFAIL and UNSUPPORTED
A `lit` condition line is now a comma-separated list of boolean expressions. 
Comma-separated expressions act as if each expression were on its own 
condition line:
For REQUIRES, if every expression is true then the test will run. 
For UNSUPPORTED, if every expression is false then the test will run. 
For XFAIL, if every expression is false then the test is expected to succeed. 
As a special case "XFAIL: *" expects the test to fail.

Examples:
# Test is expected fail on 64-bit Apple simulators and pass everywhere else
XFAIL: x86_64 && apple && !macosx
# Test is unsupported on Windows and on non-Ubuntu Linux 
# and supported everywhere else
UNSUPPORTED: linux && !ubuntu, system-windows

Syntax: 
* '&&', '||', '!', '(', ')'. 'true' is true. 'false' is false.
* Each test feature is a true identifier. 
* Substrings of the target triple are true identifiers for UNSUPPORTED 
 and XFAIL, but not for REQUIRES. (This matches the current behavior.)
* All other identifiers are false.
* Identifiers are [-+=._a-zA-Z0-9]+
