[WebAssembly] Error out on invalid personality functions Without explicitly checking and erroring out, an invalid personality function, which is not `__gxx_wasm_personality_v0`, caused a segmentation fault down the line because `WasmEHFuncInfo` was not created. This explicitly checks the validity of personality functions in functions with EH pads and errors out explicitly with a helpful error message. This also adds some more assertions to ensure `WasmEHFuncInfo` is correctly created and non-null. Invalid personality functions wouldn't be generated by our Clang, but can be present in handwritten ll files, and more often, in files transformed by passes like `metarenamer`, which is often used with `bugpoint` to simplify names in `bugpoint`-reduced files.

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.
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.
Join the LLVM Discourse forums, Discord chat, or #llvm IRC channel on OFTC.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
