* Make Semantics test doconcurrent01.f90 an expected failure pending a fix for a problem in recognizing a PURE prefix specifier for a specific procedure that occurs in new intrinsic module source code, * review update * review update * Increase support for intrinsic module procedures The f18 standard defines 5 intrinsic modules that define varying numbers of procedures, including several operators: 2 iso_fortran_env 55 ieee_arithmetic 10 ieee_exceptions 0 ieee_features 6 iso_c_binding There are existing fortran source files for each of these intrinsic modules. This PR adds generic procedure declarations to these files for procedures that do not already have them, together with associated specific procedure declarations. It also adds the capability of recognizing intrinsic module procedures in lowering code, making it possible to use existing language intrinsic code generation for intrinsic module procedures for both scalar and elemental calls. Code can then be generated for intrinsic module procedures using existing options, including front end folding, direct inlining, and calls to runtime support routines. Detailed code generation is provided for several procedures in this PR, with others left to future PRs. Procedure calls that reach lowering and don't have detailed implementation support will generate a "not yet implemented" message with a recognizable name. The generic procedures in these modules may each have as many as 36 specific procedures. Most specific procedures are generated via macros that generate type specific interface declarations. These specific declarations provide detailed argument information for each individual procedure call, similar to what is done via other means for standard language intrinsics. The modules only provide interface declarations. There are no procedure definitions, again in keeping with how language intrinsics are processed. This patch is part of the upstreaming effort from fir-dev branch.
