This avoids duplication and simplifies the code in several places
without increasing the size of the symbol union (at least not
above the assert'd limit of 120 bytes).

When we go to destroy the process, we first try to halt it, if
we succeeded and the target stopped, we want to clear out the
thread plans and breakpoints in case we still need to resume to complete
killing the process. If the target was exited or detached, it's
pointless but harmless to do this. But if the state is eStateInvalid -
for instance if we tried to interrupt the target to Halt it and that
fails - we don't want to keep trying to interact with the inferior,
so we shouldn't do this work.
This change explicitly checks eStateStopped, and only does the pre-resume
cleanup if we did manage to stop the process.
Debug info sections need R_WASM_FUNCTION_OFFSET_I32 relocs (with FK_Data_4 fixup
kinds) to refer to functions (instead of R_WASM_TABLE_INDEX as is used in data
sections). Usually this is done in a convoluted way, with unnamed temp data
symbols which target the start of the function, in which case
WasmObjectWriter::recordRelocation converts it to use the section symbol
instead. However in some cases the function can actually be undefined; in this
case the dwarf generator uses the function symbol (a named undefined function
symbol) instead. In that case the section-symbol transform doesn't work and we
need to generate the correct reloc type a different way. In this change
WebAssemblyWasmObjectWriter::getRelocType takes the fixup section type into
account to choose the correct reloc type.

It turns out that during training, the time required to parse the
textual protobuf of a training log is about the same as the time it
takes to compile the module generating that log. Using binary protobufs
instead elides that cost almost completely.

This is the first step to support software pipeline for scf.for loops.
This is only the transformation to create pipelined kernel and

The scheduling needs to be given by user as many different algorithm

This currently doesn't handle loop arguments, this will be added in a

As discussed on D105251, currently the compiler does not support
multiple metadata attachments on instructions having the same
identifier, whereas it does for global objects. Note this in the
Language Reference manual for clarity.
See D105251 for discussions of history behind this divergence, and the
complexities and possible approaches of adding this support to
instructions in the future.

We need the compiler generated variable to override the weak symbol of
the same name inside the profile runtime, but using LinkOnceODRLinkage
results in weak symbol being emitted in which case the symbol selected
by the linker is going to depend on the order of inputs which can be
fragile.
This change replaces the use of weak definition inside the runtime with
a weak alias. We place the compiler generated symbol inside a COMDAT
group so dead definition can be garbage collected by the linker.
We also disable the use of runtime counter relocation on Darwin since
Mach-O doesn't support weak external references, but Darwin already uses
a different continous mode that relies on overmapping so runtime counter
relocation isn't needed there.

RISCV would prefer a sign extended constant since that works better
with our constant materialization. We have an existing TLI hook we
use to control sign extension of setcc operands in type legalization.
That hook happens to do the right check we need here, but might be
straying from its original purpose. With only RISCV defining this
hook in tree, I wasn't sure if it was worth adding another hook
with identical behavior.
This is an alternative to D105785 where I tried to handle this in
the RISCV backend by not creating ANY_EXTENDs in some places.

This patch adds the `-faltivec-src-compat=mixed` option to the
`builtins-ppc-altivec.c` test.
Currently, the default for `-faltivec-src-compat` is `mixed`. The reason we
explicitly specify `mixed` to the RUN lines of this test is because eventually,
the default will set to `xl`.
Having the default as `xl` changes the CHECKs of this test slightly, as it
reorders some of the `vector bool` and `vector pixel` CHECKs (since under the
`xl` option, `vector bool` and `vector pixel` are treated in the same way as
other vector scalars). Explicitly specifying `mixed` ensures that we are testing
pre-existing Clang behaviour.

This removes the promotion of NEON AND, OR and XOR nodes to v2i32/v4i32,
treating them the same as the AArch64 and MVE backends where we just add
the relevant patterns for each legal type. This prevents a lot of
bitcasts from being added to the DAG, which have the potential to make
optimizations more difficult. It does mean adding extra patterns, and
some codegen can change due to the types now being legal, not promoted.

This patch adds a new pass called LNICM which is a LoopNest version of LICM and a test case to show how LNICM works.
Basically, LNICM only hoists invariants out of loop nest (not a loop) to keep/make perfect loop nest. This enables later optimizations that require perfect loop nest.
