Implicit def operands are needed when we spill partially undef super registers by each individual subregister. The implicit-def operands will allow us to lower spills without the verifier complaining. Currently, we are overzeously attaching implicit operands, when we really only need them on the first sub reg spill op. By more selectively attached the implicit ops, we will free up some unneeded dependencies for the post-ra scheduler.
Moreover, this enables a previously incorrect optimization / resolves a correctness issue in indirectCopyToAGPR. When lowering AGPR copies on GFX908, we can improve CodeGen by reusing accvgpr_writes.

If there are two or more similar predecessors, like the test case in the bug

critical edges. But we can move all loads in successor blocks into predecessors.

[WebAssembly] Ensure 'end_function' in functions
Local info is supposed to be emitted in the start of every function.
When there are locals, `.local` section should be present, and we emit
local info according to the section.
If there is no locals, empty local info should be emitted. This empty
local info is emitted whenever a first instruction is emitted within a
function without encountering a `.local` section. If there is no
instruction, `end_function` pseudo instruction should be present and the
empty local info will be emitted when parsing the pseudo instruction.
The following assembly is malformed because the function `test` doesn't
have an `end_function` at the end, and the parser doesn't end up
emitting the empty local info needed. But currently we don't error out
and silently produce an invalid binary.
```
.functype test () -> ()
test:
```
This patch adds one extra state to the Wasm assembly parser,
`FunctionLabel` to detect whether a function label is parsed but not
ended properly when the next function starts or the file ends.
It is somewhat tricky to distinguish `FunctionLabel` and
`FunctionStart`, because it is not always possible to ensure the state
goes from `FunctionLabel` -> `FunctionStart`. `.functype` directive does
not seem to be mandated before a function label, in which case we don't
know if the label is a function at the time of parsing. But when we do
know the label is function, we would like to ensure it ends with an
`end_function` properly. Also we would like to error out when it does
not.
For example,
```
.functype test() -> ()
test:
```
We should error out for this because we know `test` is a function and it
doesn't end with an `end_function`. This PR fixes this.
```
test:
```
We don't error out for this because there is no info that `test` is a
function, so we don't know whether there should be an `end_function` or
not.
```
test:
.functype test() -> ()
```
We error out for this currently already, because we currently switch to
`FunctionStart` state when we first see `.functype` directive after its
label definition.

This CL increases the memory mappings to 4TB for
high app, 1.3TB for mid app, and 10TB for low app. Note
that tsan's 44-bit pointer compression/decompression imposes
a 16TB limit on the combined size of the app mappings, making
this set of mappings more or less maximal.

[lld-macho] Prevent assertions for aliases to weak_def_can_be_hidden symbols
In https://reviews.llvm.org/D137982 we found that on Mach-O private
aliases could trigger an assert in lld when the aliasee was a
weak_def_can_be_hidden symbol.
This appears to be incorrect, and should be allowed in Mach-O.
Disallowing this behavior is also inconsistent with how ld64 handles
a private alias to weak_def_can_be_hidden symbols.
This patch removes the assert and tests that LLD handles such aliases
gracefully.

[libc++] Remove HIDE_FROM_ABI from virtual functions
_LIBCPP_HIDE_FROM_ABI (which is what _LIBCPP_INLINE_VISIBILITY is) uses
ABI tags to avoid ODR violations when linking together object files
compiled against different versions of libc++. However, pointer
authentication uses the mangled name of the function to sign the
function pointer in the vtable, which means that the ABI tag effectively
changes how the pointers are signed.
This leads to PAC failures when passing an object that holds one of these
pointers in its vtable across an ABI boundary: one side will sign the
pointer using one function mangling (with one ABI tag), and the other
side will authenticate the pointer expecting it to have a different
mangled name, which won't work.
To make sure this does not regress in the future, this patch also adds
a clang-query test to detect incorrect applications of _LIBCPP_HIDE_FROM_ABI.
