larger timeout value. This really isn't very good because it will
still be susceptible to machine performance.
While we are here also fix a bug in validation of
`maxIndividualTestTime` where previously it wasn't checked if the
type was an int.

The program used to be used in `quick_then_slow.py` but that was
removed in r328702. The tests always run `slow.py` on its own but
this doesn't really test additional code so we'll just drop running
`slow.py` so the tests run faster.

If the system is under heavy load 1 second might not be long enough
for it to produce output which could lead to spurious test failures.
What matters is that the right test cases reach a timeout.

Some ISA's such as microMIPS32(R6) have instructions which are near identical
for code generation purposes, e.g. xor and xor16. These instructions take the
same value types for operands and return values, have the same
instruction predicates and map to the same ISD opcode. (These instructions do
differ by register classes.)
In such cases, the FastISel generator rejects the instruction definition.
This patch borrows the 'FastIselShouldIgnore' bit from rL129692 and enables
applying it to an instruction definition.

Introduced CreateMemTempWithoutCast and CreateTemporaryAllocaWithoutCast to emit alloca
without casting to default addr space.
ActiveFlag is a temporary variable emitted for clean up. It is defined as AllocaInst* type and there is
a cast to AlllocaInst in SetActiveFlag. An alloca casted to generic pointer causes assertion in
SetActiveFlag.
Since there is only load/store of ActiveFlag, it is safe to use the original alloca, therefore use
CreateMemTempWithoutCast is called.

MipsLongBranchPass and MipsHazardSchedule passes are joined to one pass
because of mutual conflict. When MipsHazardSchedule inserts 'nop's, it
potentially breaks some jumps, so they have to be expanded to long
branches. When some branch is expanded to long branch, it potentially
creates a hazard situation, which should be fixed by adding nops.
New pass is called MipsBranchExpansion, it combines these two passes,
and runs them alternately until one of them reports no changes were made.

This enables us to detect more fast path sdiv cases under cost analysis.
This patch also enables us to handle non-uniform-constant pow2 cases for X86 SDIV costs.

return function y(): a is B { ... };
}
Breaking before the `is` above breaks TypeScript parsing the code. This

Summary:
When lowerswitch merge several cases into a new default block it's not
updating the PHI nodes accordingly. The code that update the PHI nodes
for the default edge only update the first entry and do not remove the
remaining ones, to make sure the number of entries match the number of
predecessors.
This is easily fixed by replacing the code that update the PHI node with
the already existing utility function for updating PHI nodes.

Summary:
In LoopVersioning::addPHINodes we need to iterate over all
users for a value "Inst", and if the user is outside of the
VersionedLoop we should replace the use of "Inst" by using
the value "PN" instead.
Replacing the use of "Inst" for a user of "Inst" also means
that Inst->users() is modified. So it is not safe to do the
replace while iterating over Inst->users() as we used to do.
This patch splits the task into two steps. First we iterate
over Inst->users() to find all users that should be updated.
Those users are saved into a local data structure on the stack.
And then, in the second step, we do the actual updates. This
time iterating over the local data structure.

Partially cleans up the mess used for lowering of the d16

For both argument and return types, promote illegal types like i24 to i32,

This patch continues a series of patches that decrease time spent by
GlobalISel in its InstructionSelect pass by roughly 60% for -O0 builds
for large inputs as measured on sqlite3-amalgamation
(http://sqlite.org/download.html) targeting AArch64.
This commit specifically removes number of operands checks that are
redundant if the instruction's opcode already guarantees that number
of operands (or more), and also avoids any kind of checks on a def
operand of a nested instruction as everything about it was already
checked at its use.
The expected performance implication is about 3% off InstructionSelect
comparing to the baseline (before the series of patches)
This patch also contains a bit of NFC changes required for further
patches in the series.
Every commit planned shares the same Phabricator Review.

Summary:
MCTargetDesc/AMDGPUMCTargetDesc.h contains enums for all the instuction
and register defintions, which are huge so we only want to include
them where needed.
This will also make it easier if we want to split the R600 and GCN
definitions into separate tablegenerated files.
I was unable to remove AMDGPUMCTargetDesc.h from SIMachineFunctionInfo.h
because it uses some enums from the header to initialize default values
for the SIMachineFunction class, so I ended up having to remove includes of
SIMachineFunctionInfo.h from headers too.

We've seen some cases on macOS where you go to instruction single
step (over a breakpoint), and single step returns but the instruction
hasn't been executed (and the pc hasn't moved.) The ThreadPlanStepOverBreakpoint
used to handle this case by accident, but the patches to handle two adjacent
breakpoints broke that accident.
This patch fixes the logic of ExplainsStop to explicitly handle the case where
the pc didn't move. It also adds a WillPop that re-enables the breakpoint we
were stepping over. We never want an unexpected path through the plan to
fool us into not doing that.
I have no idea how to make this bug happen. It is very inconsistent when it
occurs IRL. We really need a full MockProcess Plugin before we can start to write
tests for this sort of system hiccup.
