[AMDGPU][True16][GlobalISel] Fix v2*16 build_vector patterns (#151496)

- Pattern with IMPLICIT_DEF failed to generate an entry in MatchTable and
did not report an error, just silently failed. This is fixed by casting
IMPLICIT_DEF to appropriate type. This also fixes selecting
"build_vector s16, undef" for GlobalISel with True16.
- Add pattern for "build_vector undef, s16" that will work for GlobalISel.
True16 GlobalISel has a G_TRUNC that it needs to deal with.
- Use REG_SEQUENCE for Real16 patterns instead of V_LSHLREV_B32_e64 to
generate more optimal code.

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.

Getting in touch

Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
