Oliver Stannard 64c167db7a [AArch64] Add ARMv8.2-A new AT instruction variants
ARMv8.2-A adds new variants of the "at" (address translate) system
instruction, which take the PSTATE.PAN bit (added in ARMv8.1-A). These
are a required part of ARMv8.2-A, so no additional subtarget features
are required.

Martell Malone d12292480a ARM: address WOA unsigned division overflow crash
Building on r253865 the crash is not limited to signed overflows.

Disable custom handling of unsigned 32-bit and 64-bit integer divide.
Add test cases for both 32-bit and 64-bit unsigned integer overflow.

Oliver Stannard 911ea20f07 [AArch64] Add ARMv8.2-A UAO PSTATE bit
ARMv8.2-A adds a new PSTATE bit, PSTATE.UAO, which allows the LDTR/STTR
instructions to behave the same as LDR/STR with respect to execute-only
pages at higher privilege levels. New variants of the MSR/MRS
instructions are added to allow reading and writing this bit. It is a
required part of ARMv8.2-A, so no additional subtarget features are
required.

Oliver Stannard 1a81cc9f43 [AArch64] Add ARMv8.2-A persistent memory instruction
ARMv8.2-A adds the "dc cvap" instruction, which is a system instruction
that cleans caches to the point of persistence (for systems that have
persistent memory). It is a required part of ARMv8.2-A, so no additional
subtarget features are required.

Oliver Stannard 48b43741d0 [AArch64] Add ARMv8.2-A ID_A64MMFR2_EL1 register
ARMv8.2-A adds a new ID register, ID_A64MMFR2_EL1, which behaves in the
same way as ID_A64MMFR0_EL1 and ID_A64MMFR1_EL1. It is a required part
of ARMv8.2-A, so no additional subtarget features are required.

Oliver Stannard 7cc0c4e675 [AArch64] Add subtarget features for ARMv8.2-A
This adds subtarget features for ARMv8.2-A, which builds on (and
requires the features from) ARMv8.1-A. Most assembler-visible features
of ARMv8.2-A are system instructions, and are all required parts of the
architecture, so just depend on the HasV8_2aOps subtarget feature. There
is also one large, optional feature, which adds 16-bit floating point
versions of all existing floating-point instructions (VFP and SIMD),
this is represented by the FeatureFullFP16 subtarget feature.

Daniel Sanders fbb6a237ba [mips][ias] Explicitly disable IAS on tests that depend on not assembling.
Summary:
no-odd-spreg-msa.ll: This test deliberately uses an odd-numbered register
in inline assembly and expects the compiler to insert a move to an
even-numbered register.

inlineasm-operand-code.ll and inlineasm_constraint.ll:
Checks for IAS's output will be added once a matcher bug is resolved. This bug
causes the canonical output emitted by IAS to be incorrect for uimm16 constants
with the MSB set. We will still need the non-IAS checks at this point since
these tests primarily test formatting of operands.

Sanjoy Das bcd150362a [OperandBundles] Treat "deopt" operand bundles specially
Teach LLVM optimize to more precisely in the presence of "deopt" operand
bundles.  "deopt" operand bundles imply that the call they're attached
to is at least `readonly` (i.e. they don't imply clobber semantics), and
they don't capture their bundle operands.

Xinliang David Li ed966771da [PGO] Implement ValueProfiling Closure interfaces for runtime value profile data
This is one of the many steps to commonize value profiling support between profile
runtime and compiler/llvm tools.

After this change, profiler runtime now can share the same C APIs to do VP
serialization/deseriazation with LLVM host tools (and produces value data
in identical format between indexed and raw profile).

It is not yet enabled in profiler runtime yet.

Also added a unit test case to test runtime profile data serialization/deserialization
interfaces implemented using common closure code.

Dan Gohman fb3e0594e4 [WebAssembly] Use a physical register to describe ARGUMENT liveness.
Instead of trying to move ARGUMENT instructions back up to the top after
they've been scheduled or sunk down, use a fake physical register to
create a liveness constraint that prevents ARGUMENT instructions from
moving down in the first place. This is still not entirely ideal, however
it is more robust than letting them move and moving them back.
