[flang][OpenMP] Account for using different versions for modifier checks
When a modifier from a past/future version is accepted, use its properties
from the nearest version in which it is allowed.
[flang][OpenMP] Create generic interfaces for "container" entities
In short, clauses are containers of modifiers, and directives are
containers of clauses. With the abstractions in place, clauses and
modifiers look almost the same from the point of view of syntactic
properties.
Use these functions to implement generic GetAllowedElements and
GetElementVersionRange functions.
[flang][OpenMP] Properly use GetAllowedElements (#229523)
Allowed elements are not just those explicitly listed, but also those
from the union of allowed sets.
For example, the set of modifiers allowed on a clause are those that
are listed on a given clause, plus the union of all modifier sets that
the clause allows.
[VPlan] Generalize getLoadStoreValueType and infer the opcode (NFC). (#233293)
Accept VPInstruction as well as VPReplicateRecipe and determine load
versus store with vputils::getOpcode instead of a caller-supplied
boolean.
[libc][math] Add float-only implementation of tanf (#233046)
Reorganize tanf in the same way as sinf and cosf (#226529):
src/__support/math/tanf.h now selects the implementation, and
tanf_<type>_eval.h implements tanf with <type> as the intermediate
computational type. The existing implementation moves unchanged to
tanf_double_eval.h.
The new float-only implementation in tanf_float_eval.h is selected
under the same conditions as sinf/cosf float_eval:
LIBC_MATH_SKIP_ACCURATE_PASS, LIBC_MATH_SMALL_TABLES or
LIBC_MATH_INTERMEDIATE_COMP_IN_FLOAT, and FMA. It reuses the float range
reduction and the SIN_K_PI_OVER_8 table from sincosf_float_eval.h and
computes:
tan(x) = (sin_k + cos_k * tan(y)) / (cos_k - sin_k * tan(y)),
with x = k * pi/8 + y, |y| <= pi/16, and tan(y) approximated by a
degree-9

[LV,LLE] Add tests for checks with versioned strides (NFC) (#233276)
Add tests for trip counts rewritten using versioned strides and for the
stride check on a possibly poison stride.
[ARM] Fix miscompile in MAC for 64b values (#231702)
AddCombineTo64BitSMLAL16 is invoked from PerformADDECombine where the
combined node N is AddeNode, but it returned SDValue(AddcNode, 0).
Because RV.getNode() != N, DAGCombiner::Run did not stop replacing and
called DAG.ReplaceAllUsesWith(AddeNode, AddcNode), replacing uses of
the high-word carry/overflow flag (AddeNode, 1) with the low-word
addition flag (AddcNode, 1).
