One of the phases of SelectionDAG is LegalizeVectors. We don't need to sort the DAG and copy nodes around if there are no vector ops.

Speeds up the compilation time of SelectionDAG on a big scalar workload by ~8%.

Fixed an issue where if we got a 'A' async packet back from debugserver, we would resend the last continue command. We now correctly identify the packet as async (just like the 'O' stdout async packet) and we don't resend the continue command.

The thread plans run before the event is broadcast, so they should be calling ShouldStopSynchronous on any Stop Info's
they want to check.  The full ShouldStop should only be called on the public side of the event system.

The assembler historically didn't make use of any target features, but this has
changed when support for old CPUs that don't support long nops was added.

Some attributes make sense only on the function or on the call site, but not
both. Make this distinction here.

the back end and so need to pass it through to codegen.

Also make the methods file static so we can use them in other places.

This Decl shouldn't be the canonical Decl; it should be the Decl used by
the CXXBaseSpecifier in the subclass. Unfortunately, that means continuing
to throw getCanonicalDecl() on all comparisons.

This fixes MemRegion::getAsOffset's use of ASTRecordLayout when redeclarations
are involved.

This is because the order of the entities in the vector can change in some (uncommon) cases.

This may seem counter-intuitive but the POD-like optimization helps when the
vectors grow into multimegabyte buffers. SmallVector calls realloc which knows
how to twiddle virtual memory bits and avoids large copies.

Introduce a new AST Decl node "EmptyDecl" to model empty-declaration. Have attributes from attribute-declaration appertain
to the EmptyDecl node by creating the AST representations of these attributes and attach them to the EmptyDecl node so these
attributes can be sema checked just as attributes attached to "normal" declarations.

Add an ability to specify custom documentation block comment commands via a new
class CommentOptions.  The intention is that this class will hold future
customizations for comment parsing, including defining documentation comments
with specific numbers of parameters, etc.

CommentOptions instance is a member of LangOptions.

CommentOptions is controlled by a new command-line parameter
-fcomment-block-commands=Foo,Bar,Baz.
