[clang][NVPTX] Add builtins and intrinsics for conversions of new FP types (#134345)

This change:
- Adds NVVM intrinsics and clang builtins for the cvt instruction
variants of types (FP6) `.e2m3x2`, `.e3m2x2`, and (FP8) `.ue8m0x2`
introduced in PTX 8.6 for `sm_100a`, `sm_101a`, and `sm_120a`.
- Adds clang builtins for cvt instruction variant of type tf32.

Tests are added in `NVPTX/convert-sm100a.ll` and
`clang/test/CodeGen/builtins-nvptx.c` and verified through ptxas 12.8.0.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
