construct.

OpenMP 5.0 introduced new clause for declare target directive, device_type clause, which may accept values host, nohost, and any. Host means
that the function must be emitted only for the host, nohost - only for
the device, and any - for both, device and the host.

929af67361 [Lex] Allow to consume tokens while preprocessing
Summary:
By adding a hook to consume all tokens produced by the preprocessor.
The intention of this change is to make it possible to consume the
expanded tokens without re-runnig the preprocessor with minimal changes
to the preprocessor and minimal performance penalty when preprocessing
without recording the tokens.

The added hook is very low-level and reconstructing the expanded token
stream requires more work in the client code, the actual algorithm to
collect the tokens using this hook can be found in the follow-up change.

0336c75c36 [OpenMP 5.0] Parsing/sema support for from clause with mapper modifier.
This patch implements the parsing and sema support for the OpenMP
'from'-clause with potential user-defined mappers attached.
User-defined mappers are a new feature in OpenMP 5.0. A 'from'-clause
can have an explicit or implicit associated mapper, which instructs the
compiler to generate and use customized mapping functions. An example is
shown below:

    struct S { int len; int *d; };
    #pragma omp declare mapper(id: struct S s) map(s, s.d[0:s.len])
    struct S ss;
    #pragma omp target update from(mapper(id): ss) // use the mapper with name 'id' to map ss from device

a6e8d5e554 PR40642: Fix determination of whether the final statement of a statement
expression is a discarded-value expression.

Summary:
We used to get this wrong in three ways:

1) During parsing, an expression-statement followed by the }) ending a
   statement expression was always treated as producing the value of the
   statement expression. That's wrong for ({ if (1) expr; })
2) During template instantiation, various kinds of statement (most
   statements not appearing directly in a compound-statement) were not
   treated as discarded-value expressions, resulting in missing volatile
   loads (etc).
3) In all contexts, an expression-statement with attributes was not
   treated as producing the value of the statement expression, eg
   ({ [[attr]] expr; }).

Also fix incorrect enforcement of OpenMP rule that directives can "only
be placed in the program at a position where ignoring or deleting the
directive would result in a program with correct syntax". In particular,
a label (be it goto, case, or default) should not affect whether
directives are permitted.

251e1488e1 [OpenMP 5.0] Parsing/sema support for "omp declare mapper" directive.
This patch implements parsing and sema for "omp declare mapper"
directive. User defined mapper, i.e., declare mapper directive, is a new
feature in OpenMP 5.0. It is introduced to extend existing map clauses
for the purpose of simplifying the copy of complex data structures
between host and device (i.e., deep copy). An example is shown below:

    struct S {  int len;  int *d; };
    #pragma omp declare mapper(struct S s) map(s, s.d[0:s.len]) // Memory region that d points to is also mapped using this mapper.

2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

fb6deeb984 Refactor the way we handle diagnosing unused expression results.
Rather than sprinkle calls to DiagnoseUnusedExprResult() around in places where we want diagnostics, we now diagnose unused expression statements and full expressions in a more generic way when acting on the final expression statement. This results in more appropriate diagnostics for [[nodiscard]] where we were previously lacking them, such as when the body of a for loop is not a compound statement.

This patch fixes PR39837.

832c4afe00 [CodeComplete] Clearly distinguish signature help and code completion.
Summary:
Code completion in clang is actually a mix of two features:
- Code completion is a familiar feature. Results are exposed via the
  CodeCompleteConsumer::ProcessCodeCompleteResults callback.
- Signature help figures out if the current expression is an argument of
  some function call and shows corresponding signatures if so.
  Results are exposed via CodeCompleteConsumer::ProcessOverloadCandidates.

This patch refactors the implementation to untangle those two from each
other and makes some naming tweaks to avoid confusion when reading the
code.

The refactoring is required for signature help fixes, see D51038.

The only intended behavior change is the order of callbacks.
ProcessOverloadCandidates is now called before ProcessCodeCompleteResults.

f3c832a970 [OpenMP] Fix handling of clause on wrong directive, by Joel. E. Denny
Summary:
First, this patch fixes an assert failure when, for example, "omp for"
has num_teams.

Second, this patch prevents duplicate diagnostics when, for example,
"omp for" has uniform.

This patch makes the general assumption (even where it doesn't
necessarily fix an existing bug) that it is worthless to perform sema
for a clause that appears on a directive on which OpenMP does not
permit that clause.  However, due to this assumption, this patch
suppresses some diagnostics that were expected in the test suite.  I
assert that those diagnostics were likely just distracting to the
user.
