I found these by asserting in clang for any GCCBuiltin that doesn't
require mangling and requires a constant for the builtin. This means
that intrinsics are missing which don't use GCCBuiltin, don't have
builtins defined in clang, or were missing the constant annotation in
the builtin definition.

I'm not sure what's going on with the immediates.ll test. It seems to
be intended to test invalid cases like this, but then tries to handle
some of them anyway. I've moved the cases that were inconsistent with
the GCCBuiltin definition so they don't test the codegen anymore.

Summary:
MsgPackTypes has been replaced by the lighter-weight MsgPackDocument.

Summary:
MsgPackDocument is the lighter-weight replacement for MsgPackTypes. This
commit switches AMDGPU HSA metadata processing to use MsgPackDocument
instead of MsgPackTypes.

llvm-svn: 356081
Summary:
A class that exposes a simple in-memory representation of a document of
MsgPack objects, that can be read from and written to MsgPack, read from
and written to YAML, and inspected and modified in memory. This is
intended to be a lighter-weight (in terms of memory allocations)
replacement for MsgPackTypes.
Two subsequent changes will:
1. switch AMDGPU HSA metadata to using MsgPackDocument instead of
MsgPackTypes;
2. add MsgPack AMDGPU PAL metadata via MsgPackDocument.

The feature flag alone can't be trusted since it can be passed via -mattr. Need to ensure 64-bit mode as well.
We had a 64 bit mode check on the instruction to make the assembler work correctly. But we weren't guarding any of our lowering code or the hooks for the AtomicExpandPass.
I've added 32-bit command lines to atomic128.ll with and without cx16. The tests there would all previously fail if -mattr=cx16 was passed to them. I had to move one test case for f128 to a new file as it seems to have a different 32-bit mode or possibly sse issue.

Because we don't currently simplify icmp with undef in DAG, bugpoint loves to introduce them during reduction.
This is a small step towards re-adding non-undef values into some of the simpler tests so that they should still test correctly and emit similar/same codegen.

rL356068 caused some minor re-orderings. Regenerate legalize-fneg.ll to
reflect this, and remove the NOLIB check lines (they're redundant given that
the RV32I and RV64I check lines generated by update_llc_test_checks.py already
demonstrate there is no libcall).

Summary:
A number of optimizations are inhibited by single-use TokenFactors not
being merged into the TokenFactor using it. This makes we consider if
we can do the merge immediately.
Most tests changes here are due to the change in visitation causing
minor reorderings and associated reassociation of paired memory
operations.
CodeGen tests with non-reordering changes:
X86/aligned-variadic.ll -- memory-based add folded into stored leaq
value.
X86/constant-combiners.ll -- Optimizes out overlap between stores.
X86/pr40631_deadstore_elision -- folds constant byte store into
preceding quad word constant store.

Attempt to combine CONCAT_VECTORS nodes, which we only really have pre-legalization.
This encourages a lot of X86ISD::SUBV_BROADCAST generation, so I've added SimplifyDemandedVectorEltsForTargetNode handling for this at the same time.
The X86ISD::VTRUNC regression in shuffle-vs-trunc-256-widen.ll will be handled in a future commit.

This follows similar logic in the ARM and Mips backends, and allows the free
use of s0 in functions without a dedicated frame pointer. The changes in
callee-saved-gprs.ll most clearly show the effect of this patch.

Summary:
This is useful because otherwise there's no easy way to distinguish #pragma
packed(N) from attribute(packed, aligned(N)) that isn't looking at field
offsets (since pragma packed() also creates a packed attribute).

Checking whether two regions are the same is a partially decidable problem:
either we know for sure that they are the same or we cannot decide. A typical
case for this are the symbolic regions based on conjured symbols. Two
different conjured symbols are either the same or they are different. Since
we cannot decide this and want to reduce false positives as much as possible
we exclude these regions whenever checking whether two containers are the
same at iterator mismatch check.

Summary:
In my next step at cleaning up modify-python-lldb.py, I started focusing
on equality comparison. To my surprise, I found out that both python and
c++ versions of the SBType class implement equality comparison, but each
one does it differently. While the python version was implemented in
terms of type name equality, the C++ one used a deep comparison on the
underlying objects.
Removing the python version caused one test to fail (TestTypeList). This
happened because the c++ version of operator== boiled down to
TypePair::operator==, which contains two items: the compiler_type and
type_sp. In this case, the compiler_type was identical, but one of the
objects had the type_sp field unset.
I tried fixing the code so that both objects keep their type_sp member,
but it wasn't easy, because there are so many operations which just work
with the CompilerType types, and so any operation on the SBType (the
test in question was doing GetPointeeType on the type of one variable
and expecting it to match the type of another variable), cause that
second member to be lost.
So instead, here I relax the equality comparison on the TypePair
class. Now, this class ignores the type_sp for the purposes of
comparison, and uses the CompilerType only. This seems reasonable, as
each TypeSP is able to convert itself to a CompilerType.

Summary:
This patch fixes several small problems with external layouts support in
`MicrosoftRecordLayoutBuilder`:
- aligns properly the size of a struct that ends with a bit field. It was
aligned on byte before, not on the size of the field, so the struct size was
smaller than it should be;
- adjusts the struct size when injecting a vbptr in the case when there were no
bases or fields allocated after the vbptr. Similarly, without the adjustment
the struct was smaller than it should be;
- the same fix as above for the vfptr.
All these fixes affect the non-virtual size of a struct, so they are tested
through non-virtual inheritance.

To provide mapping between standard and microMIPS R6 variants of the
`sw` command we have to rename SWSP_xxx commands from "sw" to "swsp".
Otherwise `tablegen` starts to show the error `Multiple matches found
for `SW'`. After that to restore printing SWSP command as `sw`, I add
an appropriate `MipsInstAlias` instance.
We also need to implement "size reduction" for microMIPS R6. But this
task is for separate patch. After that the `micromips-lwsp-swsp.ll` test
case will be extended.

AVX1 broadcasts were failing as we were adding bitcasts that caused MayFoldLoad's hasOneUse to return false.
This patch stops introducing bitcasts so early and also replaces the broadcast index scaling through bitcasts (which can't succeed in some cases) to instead just keep track of the bitoffset which can be converted back to the broadcast index later on.
