Krasimir Georgiev 91700e0793 [clang-format] Fixes indentation of inner text proto messages
Summary:
Consider the text proto:
```
message {
  sub { key: value }
}
```
Previously the first `{` was TT_Unknown, which caused the inner message to be
indented by the continuation width. This didn't happen for:
```
message {
  sub: { key: value }
}
```
This is because the code to mark the first `{` as a TT_DictLiteral was only
considering the case where it marches forward and reaches a `:`.

This patch updates this by looking not only for `:`, but also for `<` and `{`.

Craig Topper b369cdbaad [X86] Expand IMUL/MUL instregexs in Intel scheduler models. Add load latency to some of them in SkylakeClient model.
The regular expressions and the imul names caused some instructions to be matched by multiple regexs creating unpredictable results.

This changes them all to use explicit instrs instead.

While doing this I also found that some instructions in Skylake were missing load latency so I fixed that too.

This makes lookupFlags more consistent with lookup (which takes the query as the
first argument) and composes better in practice, since lookups are usually
linearly chained: Each lookupFlags can populate the result map based on the
symbols not found in the previous lookup. (If the maps were returned rather than
passed by reference there would have to be a merge step at the end).

Aditya Nandakumar 81c81b6426 [GISel]: Implement GlobalISel combiner API.
https://reviews.llvm.org/D41373

The various components are

GICombinerHelper contains transformations that are common to all
targets. Targets can pick and choose which transformations (at
function/opcode granularity) each pass uses via configuring a
GICombinerInfo.

GICombiner contains some common code and it does the traversal,
driving of combines, worklist management and iterating until
convergence.

GICombinerInfo is an interface with a virtual method called combine.
The combiner info will allow targets to pick and choose (or
implement their own specific combines). CombineInfos can make
use of available combines in GICombineHelper to configure the
transformations for a particular pass. Currently this approach allows
cherry picking transformations from helpers (at function/opcode
granularity) and also allows early returning on specific
transformations. Targets also get to prioritize whether target specific
combines run before/after the opt-in generic combines. Ideally we would
like this part to be configured by both C++ and Tablegen. The
CombinerInfo also has a field which indicates how to deal with
IllegalOps (ie - should we allow to create them/or legalize them?).

A CombinerPass would configure a CombinerInfo, create the GICombiner
with the Info, and call
GICombiner::combineMachineInstrs(MachineFunction&).
This organization is very similar to the GISelLegalizer.

sizes were updated before decrementing one of the iterators. Afterwards,
the result of decrementing the iterator was flagged as UB by the debug

Lang Hames d78ba0d4b2 [ORC] Add helpers for building orc::SymbolResolvers from legacy findSymbol-style
functions/methods that return JITSymbols.

lookupFlagsWithLegacyFn takes a SymbolNameSet and a legacy lookup function and
returns a LookupFlagsResult. It uses the legacy lookup function to search for
each symbol. If found, getFlags is called on the symbol and the flags added to
the SymbolFlags map. If not found, the symbol is added to the SymbolsNotFound
set.

lookupWithLegacyFn takes an AsynchronousSymbolQuery, a SymbolNameSet and a
legacy lookup function. Each symbol in the SymbolNameSet is searched for via the
legacy lookup function. If it is found, its getAddress function is called
(triggering materialization if it has not happened already) and the resulting
mapping stored in the query. If it is not found the symbol is added to the
unresolved symbols set which is returned at the end of the function. If an
error occurs during legacy lookup or materialization it is passed to the
query via setFailed and the function returns immediately.

Eric Fiselier 292617e700 [libc++] Fix PR20855 -- libc++ incorrectly diagnoses illegal reference binding in std::tuple.
Summary:
See https://bugs.llvm.org/show_bug.cgi?id=20855

Libc++ goes out of it's way to diagnose `std::tuple` constructions which are UB due to lifetime bugs caused by reference creation. For example:

```
// The 'const std::string&' is created *inside* the tuple constructor, and its lifetime is over before the end of the constructor call.
std::tuple<int, const std::string&> t(std::make_tuple(42, "abc"));
```

However, we are over-aggressive and we incorrectly diagnose cases such as:

```
void foo(std::tuple<int const&, int const&> const&);
foo(std::make_tuple(42, 42));
```

This patch fixes the incorrectly diagnosed cases, as well as converting the diagnostic to use the newly added Clang trait `__reference_binds_to_temporary`. The new trait allows us to diagnose cases we previously couldn't such as:

```
std::tuple<int, const std::string&> t(42, "abc");
```

Sam Clegg 67abf53961 [WebAssembly] Don't duplicate functions in table output
Previously, we were ensuring that the "output index" for
InputFunctions was unique across all symbols that referenced
a function body, but allowing the same function body to have
multiple table indexes.

Now, we use the same mechanism for table indexes as we already
do for output indexes, ensuring that each InputFunction is only
placed in the table once.

This makes the LLD output table denser and smaller, but should
not change the behaviour.

Note that we still need the `Symbol::TableIndex` member, to
store the table index for function Symbols that don't have an
InputFunction, i.e. for address-taken imports.
