We can implicitly convert RemainingVDs to an ArrayRef.  Note that
RemainingVDs is of type SmallVector<InstrProfValueData, 24>.

Implements parts of:
- P0355 Extending chrono to Calendars and Time Zones

This adds the alternate mnemonics for movrz and movrnz.

If the Count passed into writeNopData is not a multiple of four,
add a little amount of zeros before writing the NOP stream.
This makes it match the behavior of GNU binutils.

Swap out range metadata to range attribute for calls to be able to
deprecate range metadata on calls in the future.

Handle binary ops and a few other instructions in onlyFirstPartUsed;
they only use the first part if they themselves only have their first
part used.

This moves the combine of fdiv by constant to fmul out of an
'if (Options.UnsafeFPMath || Flags.hasAllowReciprocal()' block,
so that it triggers if the divide is exact. An extra check for
Recip.isDenormal() is added as multiple places make reference
to it being unsafe or slow on certain platforms.

[DAG] FoldConstantArithmetic - allow binop folding to work with differing bitcasted constants (#94863)

We currently only constant fold binop(bitcast(c1),bitcast(c2)) if c1 and c2 are both bitcasted and from the same type.

This patch relaxes this assumption to allow the constant build vector to originate from different types (and allow cases where only one operand was bitcasted).

We still ensure we bitcast back to one of the original types if both operand were bitcasted (we assume that if we have a non-bitcasted constant then its legal to keep using that type).

Ignore implicit pointer conversions that are part of a cast expression

Closes #93959

Add StrictCStandardCompliance and StrictCppStandardCompliance options
that default to true.

Closes #83732

Ignore implicit declarations and defaulted functions. Helps with issues
in generated code like, C++
spaceship operator.

Closes #93409

Based on feedback on #94863

Do not emit warnings for non-math operators.

Closes #92516

Really perform the conversion always if the flag is set and don't make
it dependent on whether we're checking the result for initialization.

This adds %set_softint and %clear_softint alias for %asr20 and %asr21
as defined in JPS1.

Decrease the uses of getFragmentList() to make it easier to change the
fragment list representation.

When we fold `(shift (shift C0, x), C1)` we can propagate flags that

Closes #94872

readNext has two variants:

- readNext<uint64_t, endian>(ptr)
- readNext<uint64_t>(ptr, endian)

This patch uses the latter to simplify readBinaryIdsInternal.  Both
forms default to unaligned.

Now that FOR exit and resume value creation is explicitly modeled in
VPlan (05e1b534, 07b33013) it doesn't depend on the first
order recurrence splice being preserved and it can now be marked as not
having side-effects. This allows removal of first-order-recurrence-splce
if the FOR is only used in the exit or as scalar ph resume value.

This patch adds initial support to the half type on RISC-V.

Apply the onlyFirstPartUsed logic generally to all per-part
VPInstructions. Note that the test changes remove the second part
of an unsued first-order recurrence splice.

Added remquof128 function. Closes #94312

This is an implementation of floating point multiplication:

It will consist of 
   - `double x double -> float`

Cppcheck recommends using a const reference for range variables in a
for-each loop.
This avoids unnecessary copying of elements, improving performance.

This broadly follows how in almost all places, we accept `(<reg>)` to
mean `0(<reg>)`, but I think these are the first like this for Jumps
rather than Loads/Stores. These are accepted by binutils but not by
