[AMDGPU] Set AS8 address width to 48 bits

Of the 128-bits of buffer descriptor only 48 bits are address bits, so
following the discussion on https://discourse.llvm.org/t/clarifiying-the-semantics-of-ptrtoint/83987/54,
the logic conclusion is to set the index width to 48 bits instead of
the current value of 128.

Most of the test changes are mechanical datalayout updates, but there
is one actual change: the ptrmask test now uses .i48 instead of .i128
and I had to update SelectionDAGBuilder to correctly extend the mask.

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
