If we have an (add X, (and (aext (shl Y, C1)), C2)), we can pull the shift through and+aext to fold into an LEA with the.
Assuming C1 is small enough and C2 masks off all of the extend bits.
This pattern showed up in D60358. And we need to handle it to prevent a regression.

These ifs were ensuring we don't have to handle types larger than 64 bits probably because we use getZExtValue in several places below them.
None of the callers of this code pass types larger than 64-bits so we can just assert instead of branching in release code.
I've also moved them earlier since we're just looking through operations that don't effect bit width.
This is prep work for some refactoring I plan to do to the (and (shl)) handling code.

Summary:
The Modifier memory operands is used in 2 cases of memory references
(H & P ExtraCodes). Rather than pass around the likely nullptr Modifier,
refactor the handling of the Modifier out from printOperand().
The refactorings in this patch:
- Don't forward declare printOperand, move its definition up.
- The diff makes it look like there's a change to printPCRelImm
(narrator: there's not).
- Create printModifiedOperand()
- Move logic for Modifier to there from printOperand
- Use printModifiedOperand in 3 call sites that actually create
Modifiers.
- Remove now unused Modifier parameter from printOperand
- Remove default parameter from printLeaMemReference as it only has 1
call site that explicitly passes a parameter.
- Remove default parameter from printMemReference, make call lone call
site explicitly pass nullptr.
- Drop Modifier parameter from printIntelMemReference, as Intel style
memory references don't support the Modifiers in question.
This will allow future changes to printOperand() to make it a pure virtual
method on the base AsmPrinter class, allowing for more generic handling
of some architecture generic constraints. X86AsmPrinter was the only
derived class of AsmPrinter to have additional parameters on its
printOperand function.

The problem is that one can't concatenate an empty list
(implied all-ones) with non-empty list here. The result
will be the non-empty list, and it won't match the length
of the ExePorts list.
The problems begin when LoadRes != 1 here,
which is the case in PdWriteResYMMPair,
and more importantly i think it will be the case for PdWriteResExPair.

```
``!listsplat(a, size)``
A list value that contains the value ``a`` ``size`` times.
Example: ``!listsplat(0, 2)`` results in ``[0, 0]``.
```
I plan to use this in X86ScheduleBdVer2.td for LoadRes handling.
This is a little bit controversial because unlike every other binary operator
the types aren't identical.

This adds a simple extra test for constant hoisting to show it's
usefulness with constant addresses like those seen in memory
mapped registers in embedded systems.
llvm-svn: 358114
Certain optimisations from ConstantHoisting and CGP rely on Selection DAG not
seeing through to the constant in other blocks. Revert this patch while we come
up with a better way to handle that.
I will try to follow this up with some better tests.

This fixes a regression from https://reviews.llvm.org/D60354. We used to
SymbolNode *Symbol = demangleEncodedSymbol(MangledName, QN);
if (Symbol) {
Symbol->Name = QN;
}
but changed that to
SymbolNode *Symbol = demangleEncodedSymbol(MangledName, QN);
if (Error)
return nullptr;
Symbol->Name = QN;
and one branch somewhere returned a nullptr without setting Error.
Looking at the code changed in r340083 and r340710 that branch looks
like a remnant from an earlier attempt to demangle RTTI descriptors
that has since been rewritten -- so just remove this branch. It
shouldn't change behavior for correctly mangled symbols.

Call lowering should use this directly instead of going through the
EVT version, but more work is needed to deal with this (mostly the
passing of the IR type pointer instead of the relevant properties in
ArgInfo).

This patch teach getTestBitOperand to look through ANY_EXTENDs when the extended bits aren't used. The test case changed here is based what D60358 did to test16 in tbz-tbnz.ll. So this patch will avoid that regression.

`Transport.h` does not include `Features.inc`. However, since it is used in a
subdirectory, it cannot directly include the header as it is not available.
Include `Features.inc` in `ClangdLSPServer.h` prior to the inclusion of
`Transport.h` which will provide the interfaces in `ClangdMain.cpp` where the
symbol `newXPCTransport` will not be defined due to it being preprocessed away
since the configuration is not passed along to the initial inclusion.

Summary:
The InlineAsm::AsmDialect is only required for X86; no architecture
makes use of it and as such it gets passed around between arch-specific
and general code while being unused for all architectures but X86.
Since the AsmDialect is queried from a MachineInstr, which we also pass
around, remove the additional AsmDialect parameter and query for it deep
in the X86AsmPrinter only when needed/as late as possible.
This refactor should help later planned refactors to AsmPrinter, as this
difference in the X86AsmPrinter makes it harder to make AsmPrinter more
generic.

Summary:
There are cases where Sema can't tell that "foo" in foo::Bar is a
namespace qualifier, like in incomplete macro expansions.
After this patch, if sema reports no specifier but it looks like there's one in
the source code, then we take it into account.
Reworked structure and comments in getQueryScopes to try to fight
creeping complexity - unsure if I succeeded.
I made the test harder (the original version also passes).
