George Burgess IV 00f70bd933 Remove redundant casts. NFC
So I wrote a clang-tidy check to lint out redundant `isa`, `cast`, and
`dyn_cast`s for fun. This is a portion of what it found for clang; I
plan to do similar cleanups in LLVM and other subprojects when I find
time.

Because of the volume of changes, I explicitly avoided making any change
that wasn't highly local and obviously correct to me (e.g. we still have
a number of foo(cast<Bar>(baz)) that I didn't touch, since overloading
is a thing and the cast<Bar> did actually change the type -- just up the
class hierarchy).

I also tried to leave the types we were cast<>ing to somewhere nearby,
in cases where it wasn't locally obvious what we were dealing with
before.

Alex Lorenz 4e1377aff0 [index] Index simple dependent declaration references
This commit implements basic support for indexing of dependent declaration
references. Now the indexer tries to find a suitable match in the base template
for a dependent member ref/decl ref/dependent type.

Faisal Vali 683b074209 Fix PR27601 by reverting [r267453] - Refactor traversal of bases in deduction of template parameters from base
This reversal is being done with r267453's author's (i.e. Richard Smith's) permission.

This fixes https://llvm.org/bugs/show_bug.cgi?id=27601 

Also, per Richard's request the examples from the bug report have been added to our test suite.

Alexey Bataev 94a4f0cb5f [OPENMP 4.0] Initial support for 'omp declare reduction' construct.
Add parsing, sema analysis and serialization/deserialization for 'declare reduction' construct.
User-defined reductions are defined as

#pragma omp declare reduction( reduction-identifier : typename-list : combiner ) [initializer ( initializer-expr )]
These custom reductions may be used in 'reduction' clauses of OpenMP constructs. The combiner specifies how partial results can be combined into a single value. The
combiner can use the special variable identifiers omp_in and omp_out that are of the type of the variables being reduced with this reduction-identifier. Each of them will
denote one of the values to be combined before executing the combiner. It is assumed that the special omp_out identifier will refer to the storage that holds the resulting
combined value after executing the combiner.
As the initializer-expr value of a user-defined reduction is not known a priori the initializer-clause can be used to specify one. Then the contents of the initializer-clause
will be used as the initializer for private copies of reduction list items where the omp_priv identifier will refer to the storage to be initialized. The special identifier
omp_orig can also appear in the initializer-clause and it will refer to the storage of the original variable to be reduced.

Benjamin Kramer 6e4f6e1f06 [AST] Turn the callbacks of lookupInBases and forallBases into a function_ref
This lets us pass functors (and lambdas) without void * tricks. On the
downside we can't pass CXXRecordDecl's Find* members (which are now type
safe) to lookupInBases directly, but a lambda trampoline is a small
price to pay. No functionality change intended.

David Blaikie ff7d47a354 Change DeclContextLookup(Const)Result to (Mutable)ArrayRef<NamedDecl*>, as per review discussion in r170365
This does limit these typedefs to being sequences, but no current usage
requires them to be contiguous (we could expand this to a more general
iterator pair range concept at some point).

Also, it'd be nice if SmallVector were constructible directly from an ArrayRef
but this is a bit tricky since ArrayRef depends on SmallVectorBaseImpl for the
inverse conversion. (& generalizing over all range-like things, while nice,
would require some nontrivial SFINAE I haven't thought about yet)

Chandler Carruth 3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

Ted Kremenek 2883175e4c Change a bunch of cases where we do "getAs<...>->doSomething()" to
"castAs<...>->doSomething()".  The analyzer was flagging these
as potential null dereferences, which is technically true.  The
invariants appear to be that these casts should never fail, so
let's use castAs<> instead and avoid a runtime check.

Douglas Gregor 4165bd6772 Implement computation of the final overriders for each virtual
function within a class hierarchy (C++ [class.virtual]p2).

We use the final-overrider computation to determine when a particular
class is ill-formed because it has multiple final overriders for a
given virtual function (e.g., because two virtual functions override
the same virtual function in the same virtual base class). Fixes
PR5973.

We also use the final-overrider computation to determine which virtual
member functions are pure when determining whether a class is
abstract or diagnosing the improper use of an abstract class. The
prior approach to determining whether there were any pure virtual
functions in a class didn't cope with virtual base class subobjects
properly, and could not easily be fixed to deal with the oddities of
subobject hiding. Fixes PR6631.
