In the Microsoft ABI, the vftable is laid out as if all methods in every
overload set were declared in reverse order of declaration at the point
of declaration of the first overload in the set.

Previously we only considered virtual methods in an overload set, but
MSVC includes non-virtual methods for ordering purposes.

Fixes PR18902.

Clang itself only emits CodeView line tables, so it seems more

IdenticalExprChecker now warns if any expressions in a logical or bitwise
chain (&&, ||, &, |, or ^) are the same. Unlike the previous patch, this
actually checks all subexpressions against each other (an O(N^2) operation,
but N is likely to be small).

This extends the checks for identical expressions to handle identical
statements, and compares the consequent and alternative ("then" and "else")
branches of an if-statement to see if they are identical, treating a single
statement surrounded by braces as equivalent to one without braces.

This does /not/ check subsequent branches in an if/else chain, let alone
branches that are not consecutive. This may improve in a future patch, but
it would certainly take more work.

This fixes one immediate bug where an expression with side-effects
could be emitted twice during a NEON call.

It also prepares the way for folding CodeGen for many of the SISD
intrinsics into a table, reducing code size and hopefully increasing
performance eventually ("binary search + few switch cases" should be
better than "lots of switch cases").

These instructions (well, the f32 ones) are supported on 32-bit ARMv8, not just
AArch64. Now that the arm_neon.td refactoring is complete, adding them is
surprisingly simple.

rdar://problem/16035743

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@201661 91177308-0d34-0410-b5e6-96231b3b80d8

We used to have special handling for isCrypto and isA64 bits in the
NeonEmitter.cpp file (it knew the former was predicated on __ARM_FEATURE_CRYPTO
and the latter on __aarch64__ and went through various contortions to make sure
the correct intrinsics were emitted under the correct guard.

This is ugly and has obvious scalability problems (e.g. vcvtX intrinsics are
needed, which are ARMv8 only but available on both, yet another category). This
patch moves the #if predicate into the arm_neon.td file directly and makes
NeonEmitter.cpp agnostic about what goes in there.

It also deduplicates arm_neon.td so that each desired intrinsic is mentioned in
just one place (necessary because of the new mechanism for creating
arm_neon.h).

There are two kinds of automatically generated tests for NEON intrinsics, both
of which can be merged without adversely affecting users.

1. We check that a valid kind of __builtin_neon_XYZ overload is requested (e.g.
   we're not asking for a float32x4_t version when it only accepts integers. Since
   the __builtin_neon_XYZ intrinsics should only be used in arm_neon.h, relaxing
   this test and permitting AArch64 types for AArch32 should not cause a problem.
   The extra arm_neon.h definitions should be #ifdefed out anyway.
2. We check that intrinsics which take immediates are actually given
   compile-time constants within range. Since all NEON intrinsics should be
   backwards compatible, these tests should be identical on AArch64 and AArch32
   anyway.

This patch, therefore, merges the separate AArch64 and 32-bit checks.

TU is not guaranteed to be initialised in all cases.  In particular if CIdx or
ast_filename is NULL (or if &TU is NULL), then clang_createTranslationUnit2 will
not initialise the out parameter out_TU.  This is followed by an assertion check
which may perform a branch based on unitialised memory.
