Summary:
Base declaration in pointer arithmetic expression is determined by
binary search with type information. Take "int *a, *b; *(a+*b)" as an
example, we determine the base by checking the type of LHS and RHS. In
this case the type of LHS is "int *", the type of RHS is "int",
therefore, we know that we need to visit LHS in order to find base
declaration.

This aims to fix a missed inlining case.
If there's a virtual call in the callee on an alloca (stack allocated object) in
the caller, and the callee is inlined into the caller, the post-inline cleanup
would devirtualize the virtual call, but if the next iteration of
DevirtSCCRepeatedPass doesn't happen (under the new pass manager), which is
based on a heuristic to determine whether to reiterate, we may miss inlining the
devirtualized call.
This enables inlining in clang/test/CodeGenCXX/member-function-pointer-calls.cpp.

FileManager.h is an expensive header (~350ms for me in isolation), so
try to do without it.
Notably, we need to avoid checking the alignment of FileEntry, which
happens for DenseMap<FileEntry*> and PointerUnion<FileEntry*>. I
adjusted the code to avoid PointerUnion, and moved the DenseMap
insertion to the .cpp file.
Globally, this only saved about ~17 includes of the related headers
because SourceManager.h still includes FileManager.h, and it is more
popular than Module.h.
When constructing a ParsedAttr the ParsedAttrInfo gets looked up in the
AttrInfoMap, which is auto-generated using tablegen. If that lookup fails then
we look through the ParsedAttrInfos that plugins have added to the registry and
check if any has a spelling that matches.

WebAssembly enforces a rule that caller and callee signatures must
match. This means that the traditional technique of passing `main`
`argc` and `argv` even when it doesn't need them doesn't work.
Currently the backend renames `main` to `__original_main`, however this
doesn't interact well with LTO'ing libc, and the name isn't intuitive.
This patch allows us to transition to `__main_argc_argv` instead.
This implements the proposal in
https://github.com/WebAssembly/tool-conventions/pull/134
with a flag to disable it when targeting Emscripten, though this is
expected to be temporary, as discussed in the proposal comments.

Summary:
User can select the version of SYCL the compiler will
use via the flag -sycl-std, similar to -cl-std.
The flag defines the LangOpts.SYCLVersion option to the
version of SYCL. The default value is undefined.
If driver is building SYCL code, flag is set to the default SYCL
version (1.2.1)
The preprocessor uses this variable to define CL_SYCL_LANGUAGE_VERSION macro,
which should be defined according to SYCL 1.2.1 standard.
Only valid value at this point for the flag is 1.2.1.

The code in llvmorg-10-init-12188-g25ce33a6e4f is a breaking change for
users of older linkers who don't pass a version parameter, which
prevents a drop-in clang upgrade. Old tools can't know about what future
tools will do, so as a general principle the burden should be new tools
to be compatible by default. Also, for comparison, none of the other
tests of Version within AddLinkArgs add any new behaviors unless the
version is explicitly specified. Therefore, this patch changes the
-platform_version behavior from opt-out to opt-in.

I made that file by pasting together several pieces, and forgot to
take out the #include <arm_mve.h> from the tops of the later ones, so
the test was pointlessly including the same header five times. NFC.

be right.
Clang recently started diagnosing ambiguity in more cases, and this
broke the build of Firefox. GCC, ICC, MSVC, and previous versions of
Clang all accept some forms of ambiguity here (albeit different ones in
each case); this patch mostly accepts anything any of those compilers
accept.

DevirtSCCRepeatedPass iteration. Needs ReviewPublic
This aims to fix a missed inlining case.

This enables inlining in clang/test/CodeGenCXX/member-function-pointer-calls.cpp.
This doesn't do anything on its own, but it's the first step towards
allowing plugins to define attributes. It does simplify the
ParsedAttrInfo generation in ClangAttrEmitter a little though.

Summary:
This commit adds the predicated MVE intrinsics for the same set of
unary operations that I added in their unpredicated forms in
* D74333 (vrint)
* D74334 (vrev)
* D74335 (vclz, vcls)
* D74336 (vmovl)
* D74337 (vmovn)
but since the predicated versions are a lot more similar to each
other, I've kept them all together in a single big patch. Everything
here is done in the standard way we've been doing other predicated
operations: an IR intrinsic called `@llvm.arm.mve.foo.predicated` and
some isel rules that match that alongside whatever they accept for the
unpredicated version of the same instruction.
In order to write the isel rules conveniently, I've refactored the
existing isel rules for the affected instructions into multiclasses
parametrised by a vector-type class, in the usual way. All those
refactorings are intended to leave the existing isel rules unchanged:
the only difference should be that new ones for the predicated
intrinsics are introduced.
The only tiny infrastructure change I needed in this commit was to
change the implementation of `IntrinsicMX` in `arm_mve_defs.td` so
that the records it defines are anonymous rather than named (and use
`NameOverride` to set the output intrinsic name), which allows me to
call it twice in two multiclasses with the same `NAME` without a
tablegen-time error.
