Peixin Qiao c4f04a126a [flang] Make real type of kind 10 target dependent
The real(10) is supported on x86_64. On aarch64, the value of
selected_real_kind(16) should be 16 rather than 10 since real(10)
is not supported on x86_64. Previously, the real type support check
is not target dependent. Support it now through the target triple
information.

Peter Klausler f329cf97f2 [flang] Change names of specific procedures of generic interfaces in intrinsic modules
Intrinsic procedures in intrinsic modules that have (or better, *are*) generic interfaces
must not have specific procedures with the same name according to the Fortran
standard (17.11.1); i.e., a user program is allowed to define a procedure
of the same name as one of these generic interfaces, even when the generic is
in scope.

V Donaldson aba0d3cd94 [flang] Intrinsic module file update
Use symbolic iostat values in iso_fortran_env.f90.
Add generic names to the interfaces in __fortran_ieee_exceptions.f90.

[flang] Increase support for intrinsic module procedures
* 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.

V Donaldson d4980803b6 [flang] Intrinsic module procedure pure prefixes
Per 7.11.1p1 - All [ieee_arithmetic and ieee_exceptions] functions are
pure and all the subroutines are impure unless otherwise stated.  Most of
these functions are elemental (and not impure), which implies pure.
Several of the remaining non-elemental functions are missing pure prefixes;
add them.

Peter Klausler 0d9b0f642b [flang] IEEE_ARITHMETIC must imply USE IEEE_EXCEPTIONS
The intrinsic module IEEE_ARITHMETIC must incorporate the public
names from the intrisic module IEEE_EXCEPTIONS.  Rename IEEE_EXCEPTIONS
to __Fortran_ieee_exceptions so that it won't clash with the
nonintrinsic namespace, establish a new intrinic IEEE_EXCEPTIONS
module that USEs it, and add a USE to IEEE_ARITHMETIC.

Updated to use STREQUAL rather than ambiguous MATCHES in
the CMakeLists.txt file.
