[flang] Escape '%' in %VAL/%REF messages (#94331)

flang/test/Semantics/call40.f90 was failing on Darwin:
actual at 27: VAL or REF are not allowed for dummy argument 'a='
  that must be passed by means of a descriptor
expect at 27: %VAL or %REF are not allowed for dummy argument 'a='
  that must be passed by means of a descriptor

When messages.Say() is called with more arguments than just the
fixed text message, the message is treated as a format string,
passed to vsnprintf. Therefore, the '%' chars in it must be
escaped.

Note that no conversion happens when there is only a fixed text
message. Escaping '%' in this case causes "%%" to be outputted.
This can be confusing for someone expecting printf-like behavior.
Processing these text messages with snprintf could solve this,
as a future improvement.

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.
