This makes it more explicit what the scope of this pass is. The name
of this pass predates fusion on tensors using tile + fuse, and hence
the confusion.

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.

This change fixes linking errors on some llvm builders.

The patch does not depend on the availability of the library functions for
memcpy/memset as it operates on LLVM intrinsics.  The optimizations are useful
on the targets that have these functions disabled (e.g. NVPTX & AMDGPU).

Added shape inference handles cases for convolution operations. This includes

we use the specified output shape when possible however will shape propagate
if the output shape attribute has dynamic values.

[SelectionDAG][RISCV] Use isSExtCheaperThanZExt to control whether sext or zext is used for constant folding any_extend.

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.

This also avoids improperly legalizing some truncating vector stores.

Changes made:
 - Stop using `isl::set::lex_le_set`. The official way to do this is to use `isl::map::lex_le_at`
 - Removed `isl::set::lex_le_set` from `isl-noexceptions.h`
