Rui Ueyama 9381eb1045 Remove lld/Support/Memory.h.
I thought for a while about how to remove it, but it looks like we
can just copy the file for now. Of course I'm not happy about that,
but it's just less than 50 lines of code, and we already have
duplicate code in Error.h and some other places. I want to solve
them all at once later.

Craig Topper 7029db0eaa [X86][SSE][AVX-512] Convert FAND/FOR/FXOR/FANDN nodes to integer operations if they are available. This will allow a bunch of patterns to be removed.
These nodes are only emitted for lowering FABS/FNEG/FNABS/FCOPYSIGN. Ideally we just wouldn't create these nodes if SSE2 or higher is available, but it was simple to just convert them in DAG combine.

For SSE2, AVX, and AVX512 with DQI this is no functional change as the execution domain fixing pass ensures the right domain is selected regardless of the ISD opcode.

For AVX-512 without DQI we end up using integer instructions since the floating point versions aren't available. But we were already doing that for any logical operations in code that didn't come from FABS/FNEG/FNABS/FCOPYSIGN so this seems no worse. And we get the benefit of being able to fold broadcasts now.

Yaxun Liu c9318c6cf2 Fix a lit test issue exposed by r290056
The test requests a target which supports cl_khr_gl_msaa_sharing since in test/PCH/ocl_types.h
it tries to enable cl_khr_gl_msaa_sharing. Therefore this test fails on targets not supporting
cl_khr_gl_msaa_sharing, e.g. ppc64, etc.

The fix is to add triple spir-unknown-unknown which supports cl_khr_gl_msaa_sharing.

Remove the additional check and UseCERTSemantics option.
Run the move-constructor-init test with both checks enabled.
Fix modernize-pass-by-value false-positive when initializing a base
class.
Add option to modernize-pass-by-value to only warn about parameters
that are already values.

Tom Stellard 7761abb64a Add custom type for PseudoSourceValue
Summary:
PseudoSourceValue can be used to attach a target specific value for "well behaved" side-effects lowered from target specific intrinsics.
This is useful whenever there is not an LLVM IR Value around when representing such "well behaved" side-effected operations in backends by attaching a MachineMemOperand with a custom PseudoSourceValue as this makes the scheduler not treating them as "GlobalMemoryObjects" which triggers a logic that makes the operation act like a barrier in the Schedule DAG.

This patch adds another Kind to the PseudoSourceValue object which is "TargetCustom". It indicates a type of PseudoSourceValue that has a target specific meaning (aka. LLVM shouldn't assume any specific usage for such a PSV).

It supports the possibility of having many different kinds of "TargetCustom" PseudoSourceValues.

We had a discussion about if this was valuable or not (in particular because there was a believe that PSV were going away sooner or later) but seems like they are not going anywhere and I think they are useful backend side.

It is not clear the interaction of this with MIRParser (do we need a target hook to parse these?) and I would like a comment from Alex about that :)

Matthias Braun e813cf457a AArch64CollectLOH: Rewrite as block-local analysis.
Re-apply r288561: Liveness tracking should be correct now after r290014.

Previously this pass was using up to 5% compile time in some cases which
is a bit much for what it is doing. The pass featured a full blown
data-flow analysis which in the default configuration was restricted to a
single block.

This rewrites the pass under the assumption that we only ever work on a
single block. This is done in a single pass maintaining a state machine
per general purpose register to catch LOH patterns.

Vedant Kumar a4bd1463c8 Retry: [BPI] Use a safer constructor to calculate branch probabilities
BPI may trigger signed overflow UB while computing branch probabilities for
cold calls or to unreachables. For example, with our current choice of weights,
we'll crash if there are >= 2^12 branches to an unreachable.

Use a safer BranchProbability constructor which is better at handling fractions
with large denominators.

Changes since the initial commit:
  - Use explicit casts to ensure that multiplication operands are 64-bit
    ints.
