By default, `__index` has type `unsigned int`. When `_LIBCPP_ABI_VARIANT_INDEX_TYPE_OPTIMIZATION` is enabled, the type of `__index` is either `unsigned char`, `unsigned short`, or `unsigned int`, depending on how many fields there are -- as small as possible. For example, when `std::variant` has only a few types, the index type is `unsigned char`, and the npos value will be interpreted by LLDB as `255` when it should be `-1`.

[RISCV][TTI] Account for constant materialization cost when costing arithmetic operations

At the IR level, we generally assume that constants are free to materialize. However, for RISCV due to some quirks of the ISA, materializing arbitrary constants can be rather expensive. We frequently fallback to constant pool loads.

We've been slowly moving in the direction of modeling the cost of the remat as part of the instruction cost. This has the effect of disincentivizing vectorization - mostly SLP - when we'd have to materialize an expensive constant.

We need better modeling of which constants are expensive and not, but the moment let's be consistent with how we model arithmetic and memory instructions. The difference between the two is that arithmetic can sometimes fold a splat operation which stores can not.

[flang] Add hlfir.associate and hlfir.end_associate definitions

These operations allow creating an HLFIR variable from a HLFIR value and
destroying it at the end of the variable lifetime.
This will both be used to implement procedure reference arguments association
when the actual is an expression, and to implement the Fortran associate
construct when the associated entity is an expression.

See https://github.com/llvm/llvm-project/blob/main/flang/docs/HighLevelFIR.md
for more details.

[CodeGen][X86] Crash fixes for "patchable-function" pass

This patch fixes crashes related with how PatchableFunction selects the instruction to make patchable:
- Ensure PatchableFunction skips all instructions that don't generate actual machine instructions.
- Handle the case where the first MachineBasicBlock is empty
- Removed support for 16 bit x86 architectures.

Instead, we evaluate them when constructing a
