Fady Ghanim 7438059a90 [OpenMP][OMPIRBuilder] Add Directives (master and critical) to OMPBuilder.
Add support for Master and Critical directive in the OMPIRBuilder. Both make use of a new common interface for emitting inlined OMP regions called `emitInlinedRegion` which was added in this patch as well.

Also this patch modifies clang to use the new directives when  `-fopenmp-enable-irbuilder` commandline option is passed.

Fangrui Song 0fbe221543 [MC][ELF] Make linked-to symbol name part of ELFSectionKey
https://bugs.llvm.org/show_bug.cgi?id=44775

This rule has been implemented by GNU as https://sourceware.org/ml/binutils/2020-02/msg00028.html (binutils >= 2.35)

It allows us to simplify

```
.section .foo,"o",foo,unique,0
.section .foo,"o",bar,unique,1  # different section
```

to

```
.section .foo,"o",foo
.section .foo,"o",bar  # different section
```

We consider the two `.foo` different even if the linked-to symbols foo and bar
are defined in the same section.  This is a deliberate choice so that we don't
need to know the section where foo and bar are defined beforehand.

Johannes Doerfert 282f5d7ad1 [Attributor] Derive memory location attributes (argmemonly, ...)
In addition to memory behavior attributes (readonly/writeonly) we now
derive memory location attributes (argmemonly/inaccessiblememonly/...).
The former is part of AAMemoryBehavior and the latter part of
AAMemoryLocation. While they are similar in nature it got messy when
they were put in a single AA. Location attributes for arguments and
floating values will follow later.

Note that both memory attributes kinds can derive readnone. If there are
no accesses AAMemoryBehavior will derive readnone. If there are accesses
but only to stack (=local) locations AAMemoryLocation will derive
readnone.

Johannes Doerfert 1228d42dda [OpenMP][Part 2] Use reusable OpenMP context/traits handling
This patch implements an almost complete handling of OpenMP
contexts/traits such that we can reuse most of the logic in Flang
through the OMPContext.{h,cpp} in llvm/Frontend/OpenMP.

All but construct SIMD specifiers, e.g., inbranch, and the device ISA
selector are define in `llvm/lib/Frontend/OpenMP/OMPKinds.def`. From
these definitions we generate the enum classes `TraitSet`,
`TraitSelector`, and `TraitProperty` as well as conversion and helper
functions in `llvm/lib/Frontend/OpenMP/OMPContext.{h,cpp}`.

The above enum classes are used in the parser, sema, and the AST
attribute. The latter is not a collection of multiple primitive variant
arguments that contain encodings via numbers and strings but instead a
tree that mirrors the `match` clause (see `struct OpenMPTraitInfo`).

The changes to the parser make it more forgiving when wrong syntax is
read and they also resulted in more specialized diagnostics. The tests
are updated and the core issues are detected as before. Here and
elsewhere this patch tries to be generic, thus we do not distinguish
what selector set, selector, or property is parsed except if they do
behave exceptionally, as for example `user={condition(EXPR)}` does.

The sema logic changed in two ways: First, the OMPDeclareVariantAttr
representation changed, as mentioned above, and the sema was adjusted to
work with the new `OpenMPTraitInfo`. Second, the matching and scoring
logic moved into `OMPContext.{h,cpp}`. It is implemented on a flat
representation of the `match` clause that is not tied to clang.
`OpenMPTraitInfo` provides a method to generate this flat structure (see
`struct VariantMatchInfo`) by computing integer score values and boolean
user conditions from the `clang::Expr` we keep for them.

The OpenMP context is now an explicit object (see `struct OMPContext`).
This is in anticipation of construct traits that need to be tracked. The
OpenMP context, as well as the `VariantMatchInfo`, are basically made up
of a set of active or respectively required traits, e.g., 'host', and an
ordered container of constructs which allows duplication. Matching and
scoring is kept as generic as possible to allow easy extension in the
future.

---

Test changes:

The messages checked in `OpenMP/declare_variant_messages.{c,cpp}` have
been auto generated to match the new warnings and notes of the parser.
The "subset" checks were reversed causing the wrong version to be
picked. The tests have been adjusted to correct this.
We do not print scores if the user did not provide one.
We print spaces to make lists in the `match` clause more legible.

Jonas Devlieghere 4f2cccc5ce [lldb/Editline] Fix mistake in HistoryOperation mapping
In 0e9b0b6d11 I introduced the
HistoryOperation enum to navigate the history. While this fixed the
behavior of HistoryOperation::Older and HistoryOperation::Newer, it
confused the mapping for HistoryOperation::Oldest and
HistoryOperation::Newest.

I tried to write a PExpect test to make sure this doesn't regress, but
I'm unable to prime the history in such a way that it recalls a known
element. I suspect this is an LLDB bug, but the  most recent entry
doesn't get update with entries from the current session. I considered
spoofing the home directory but that needs to happen before libLLDB is
loaded and you'll need to account for the widechar support. If anyone
has another suggestion I'd love to hear it.
