peter klausler a0a1a4e5c8 [flang] Improve error handling for bad characters in source
When an illegal character appears in Fortran source (after
preprocessing), catch and report it in the prescanning phase
rather than leaving it for the parser to cope with.

peter klausler cf2274b779 [flang] Allow ! and // comments after some preprocessing directives
Old-style C /*comments*/ are omitted from preprocessor directive
token sequences by the prescanner, but line-ending C++ and Fortran
free-form comments are not since their handling might depend on
the directive.  Add code to skip these line-ending comments as
appropriate in place of existing code that just skipped blanks.

Caroline Concatto 8670e49901 [flang] [LLVMify F18] Replace the use std::ostream with LLVM streams llvm::ostream
This patch replaces the occurrence of std::ostream by llvm::raw_ostream.
In  LLVM Coding Standards[1] "All new code should use raw_ostream
instead of ostream".[1]

As a consequence, this patch also replaces the use of:
   std::stringstream by llvm::raw_string_ostream or llvm::raw_ostream*
   std::ofstream by llvm::raw_fd_ostream
   std::endl by '\n' and flush()[2]
   std::cout by llvm::outs()   and
   std::cerr by llvm::errs()

It also replaces  std::strerro by llvm::sys::StrError** , but NOT in  Fortran
runtime libraries

*std::stringstream were replaced by llvm::raw_ostream in all methods that
used std::stringstream as a parameter. Moreover, it removes the pointers to
these streams.
