If llvm-symbolizer finds a malformed command, it echoes it to the standard output. New versions of binutils (starting from 2.39) allow to specify an address by a symbols. Implementation of this feature in llvm-symbolizer makes the current reaction on invalid input inappropriate. Almost any invalid command may be treated as a symbol name, so the right reaction should be "symbol not found" in such case. The exception are commands that are recognized but have incorrect syntax, like "FILE:FILE:". The utility must produce descriptive diagnostic for such input and route it to the stderr. This change implements the new reaction on invalid input and is a prerequisite for implementation of symbol lookup in llvm-symbolizer. Differential Revision: https://reviews.llvm.org/D157210
