[Flang] Do not emit numeric_storage_size into object file (#131463) The value of numeric_storage_size depends on compilation options and therefore its value is not yet known when building the builtins runtime. Instead, the parameter is folding a __numeric_storage_size() expression which is loaded into the user program. For the iso_fortran_env object file, omit the symbol as it is never used. Similar tests that ensure that __numeric_storage_size() is not folded until compiling the actual user program exist in FortranEvalutate: https://github.com/llvm/llvm-project/blob/1e6ba3cd2fe96be00b6ed6ba28b3d9f9271d784d/flang/lib/Evaluate/check-expression.cpp#L487-L492 https://github.com/llvm/llvm-project/blob/1e6ba3cd2fe96be00b6ed6ba28b3d9f9271d784d/flang/lib/Evaluate/fold-integer.cpp#L1457-L1460 Required for using CMake to compile the builtin module 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.
