IsDescriptor was returning false for a component whose shape depended
on a length parameter. Change it to return true for any array with
non-constant bounds.

Summary:
omp.h header file defines omp_null_allocator as a predefined allocator,
need to consider it also as a predefined allocator.

SPIR-V ops can mix operands and attributes in the definition. These
operands and attributes are serialized in the exact order of the definition
to match SPIR-V binary format requirements. It can cause excessive
generated code bloat because we are emitting code to handle each
operand/attribute separately. So here we probe first to check whether all
the operands are ahead of attributes. Then we can serialize all operands
together.
This removes ~1000 lines of code from the generated inc file.

These template functions are used in the serializer, where we can
actually directly query the opcode from the op's definition and
use that in the auto-generated serialization logic.
This removes a set of templates accounting for 319 lines from
the auto-generated inc file.

We rely on the combine
(sext_in_reg (v4i64 a/sext (v4i32 x)), v4i1) -> (v4i64 sext (v4i32 sext_in_reg (v4i32 x, ExtraVT)))
to avoid complex v4i64 ashr codegen, but doing so prevents v4i64 comparison mask promotion, so ensure we attempt to promote before canonicalizing the (hopefully now redundant sext_in_reg).
Helps with the poor codegen in PR45808.
Summary:
When forking in several threads, the counters were written out in using the same global static variables (see GCDAProfiling.c): that leads to crashes.
So when there is a fork, the counters are resetted in the child process and they will be dumped at exit using the interprocess file locking.
When there is an exec, the counters are written out and in case of failures they're resetted.

Enables the MVEGatherScatterLowering pass to build
pre-incrementing gathers. Incrementing writeback gathers
are built when it is possible to replace the loop increment
instruction.

Summary:
Correct instruction bitfield addresses to generate machine code correctly. Also
add some variables to represent all instructions correctly and change default
values to use registers by default.

Summary:
Conflicting types for the same section name defined in clang section
pragmas and GNU-style section attributes were not properly captured by
Clang's Sema. The lack of diagnostics was caused by the fact the section
specification coming from attributes was handled by Sema as implicit,
even though explicitly defined by the user.
This patch enables the diagnostics for section type conflicts between
those specifications by making sure sections defined in section
attributes are correctly handled as explicit.

Summary:
Section names used in clang section pragmas were not validated against
previously defined sections, causing section type conflicts to be
ignored by Sema.
This patch enables Clang to capture these section type conflicts by
using the existing Sema's UnifySection method to validate section names
from clang section pragmas.

Summary:
We used getEnclosingNamespaceContext(), which calls getParent() rather
than getLexicalParent(), so we would end up adding the "using" line in
places that do not affect the cursor location, or just return an error
when declaration was in another file.

Originally, these operations were folded only if all expressions in their
affine maps could be folded to a constant expression that can be then subject
to numeric min/max computation. This introduces a more advanced version that
partially folds the affine map by lifting individual constant expression in it
even if some of the expressions remain variable. The folding can update the
operation in place to use a simpler map. Note that this is not as powerful as
canonicalization, in particular this does not remove dimensions or symbols that
became useless. This allows for better composition of Linalg tiling and
promotion transformation, where the latter can handle some canonical forms of
affine.min that the folding can now produce.
