Extend the handling of memory intrinsics to also include non-
target-specific intrinsics, in particular masked loads and stores.
Invent "isHandledNonTargetIntrinsic" to distinguish between intrin-
sics that should be handled natively from intrinsics that can be
passed to TTI.
Add code that handles masked loads and stores and update the
testcase to reflect the results.

Scheduling information is of little value when they may disrupt the
pipeline. This patch allows omitting the scheduling information for CSR
instructions while still setting `SchedMachineModel::CompleteModel`. For
specific cases, any scheduling information added will be used by the
scheduler.

In order to select the immediate forms using the imported patterns, we need to
lower them into new G_VASHR/G_VLSHR target generic ops. Add a combine to do this
matching build_vector of constant operands.
With this, we get selection for free.
This reverts commit 4d85444b317a00a3e15da63cdb693d272c99a0cc.

1. Store intrinsic ID in ParseMemoryInst instead of a boolean flag
"IsTargetMemInst". This will make it easier to add support for
target-independent intrinsics.
2. Extract the complex multiline conditions from EarlyCSE::processNode
into a new function "getMatchingValue".

If we are going to write handler data (that is written as variable
length data following after the unwind info in .xdata), we need to
emit the handler data immediately, but for cases where no such
info is going to be written, skip emitting it right away. (Unwind
info for all remaining functions that hasn't gotten it emitted
directly is emitted at the end.)
This does slightly change the ordering of sections (triggering a
bunch of updates to DebugInfo/COFF tests), but the change should be
benign.
This also matches GCC's assembly output, which doesn't output
.seh_handlerdata unless it actually is needed.
For ARM64, the unwind info can be packed into the runtime function
entry itself (leaving no data in the .xdata section at all), but
that can only be done if there's no follow-on data in the .xdata
section. If emission of the unwind info is triggered via
EmitWinEHHandlerData (or the .seh_handlerdata directive), which
implicitly switches to the .xdata section, there's a chance of the
caller wanting to pass further data there, so the packed format
can't be used in that case.

When cross compiling with clang-cl, clang splits the INCLUDE env
variable around semicolons (clang/lib/Driver/ToolChains/MSVC.cpp,
MSVCToolChain::AddClangSystemIncludeArgs) and lld splits the
LIB variable similarly (lld/COFF/Driver.cpp,
LinkerDriver::addLibSearchPaths). Therefore, the consensus for
cross compilation with clang-cl and lld-link seems to be to use
semicolons, despite path lists normally being separated by colons
on unix and EnvPathSeparator being set to that.
Therefore, handle the LIB variable similarly in Clang, when
handling lib file arguments when driving linking via Clang.
This fixes commands like "clang-cl test.c -Fetest.exe kernel32.lib" in
a cross compilation setting. Normally, most users call (lld-)link
directly, but meson happens to use this command syntax for
has_function() tests.

This pass is like DeadCodeEliminationPass, but only does one pass
through a function instead of iterating on users of eliminated

DeadCodeEliminationPass should be used in all cases.

Configure default value of `LLVM_ENABLE_WARNINGS` in `HandleLLVMOptions.cmake`.
`LLVM_ENABLE_WARNINGS` is documented as ON by default, but `HandleLLVMOptions` assumes the default has been set somewhere else. If it has not been explicitly set, then `HandleLLVMOptions` implicitly uses OFF as a default.
This removes the various `option()` declarations in favor of a single declaration in `HandleLLVMOptions`. This will prevent the unwanted use of `-w` that is mentioned in a couple of the comments.

we don't try to gather to a different type or
