Rather than duplicating data fields, use DeclSpec directly to store
the qualifiers for the functions/methods. This change doesn't handle
attributes yet and has to be extended further.

[X86] Make the pointer arguments to avx512 gather/scatter intrinsics 'void*' to match gcc and Intel's documentation.

The avx2 gather intrinsics are documented to use 'int', 'long long', 'float', or 'double' *. So I'm leaving those. This matches gcc.

The original commit had a memory leak in the test has a leak as it doesn't
dispose of the evaluated cursor result.

This also contains the follow-up NFC refactoring commit r336591.

rdar://45893054

Original commit message:

[libclang] evalute compound statement cursors before trying to evaluate
the cursor like a declaration

This change fixes a bug in libclang in which it tries to evaluate a statement
cursor as a declaration cursor, because that statement still has a pointer to
the declaration parent.

Summary:
This way, when the generic ASTTraverser is extracted from ASTDumper,
there can't be any problem related to ordering of class members, a
concern that was raised in https://reviews.llvm.org/D55337.

This will also preserve the property that the generic traverser does not
enforce any coupling between the NodeDumper and the TreeStructure.

Summary:
r306722 added diagnostics when aligned allocation is used with deployment
targets that do not support it, but the first macosx supporting aligned
allocation was incorrectly set to 10.13. In reality, the dylib shipped
with macosx10.13 does not support aligned allocation, but the dylib
shipped with macosx10.14 does.

Windows doesn't allow common with alignment >32 bits, so these tests
were broken in windows mode.  This patch makes 'common' optional in

Alignment of __block isn't relevant to this test, remove its checking.

llvm-svn: 350644

As reported in PR33035, LLVM crashes if given a common object with an
alignment of greater than 32 bits. This is because the COFF file format
does not support these alignments, so emitting them is broken anyway.

This patch changes any global definitions greater than 32 bit alignment
to no longer be in 'common'.

Use the newly available space in the bit-fields of Stmt. Additionally store
FirstQualifierFoundInScope as a trailing object since it is most of the time
null (non-null for 2 of the 35446 CXXDependentScopeMemberExpr when parsing
all of Boost).

It would be possible to move the data for the nested-name-specifier to a
trailing object too to save another 2 pointers, however doing so did actually
regress the time taken to parse all of Boost slightly.

This saves 8 bytes + 1 pointer per CXXDependentScopeMemberExpr in the vast
majority of cases.

This assert catches places where the AST (as seen by RecursiveASTVisitor)

-Wdelete-non-virtual-dtor previously controlled two diagnostics: 1)
calling a non-virtual dtor from an abstract class, and 2) calling a
non-virtual dtor from a polymorphic class. 1) is a lot more severe
than 2), since 1) is a guaranteed crash, but 2) is just "code smell".
Previously, projects compiled with -Wall -Wno-delete-non-virtual-dtor,
which is somewhat reasonable, silently crashed on 1).

and optional placement new arguments in a trailing array. Additionally store
the range for the parenthesized type-id in a trailing object if needed since
in the vast majority of cases the type is not parenthesized (not a single new
expression in the translation unit of SemaDecl.cpp has a parenthesized type-id).
