[flang] Update the regression tests to use the new driver when enabled This patch updates most of the remaining regression tests (~400) to use `flang-new` rather then `f18` when `FLANG_BUILD_NEW_DRIVER` is set. This allows us to share more Flang regression tests between `f18` and `flang-new`. A handful of tests have not been ported yet - these are currently either failing or not supported by the new driver. Summary of changes: * RUN lines in tests are updated to use `%flang_fc1` instead of `%f18` * option spellings in tests are updated to forms accepted by both `f18` and `flang-new` * variables in Bash scripts are renamed (e.g. F18 --> FLANG_FC1) The updated tests will now be run with the new driver, `flang-new`, whenever it is enabled (i.e when `FLANG_BUILD_NEW_DRIVER` is set). Although this patch touches many files, vast majority of the changes are automatic: ``` grep -IEZlr "%f18" flang/test/ | xargs -0 -l sed -i 's/%f18/%flang_fc1/g ``` Differential Revision: https://reviews.llvm.org/D100309

[flang][windows] Run regression tests under Windows. NFCI. Allow the lit test suite to run under Windows. This encompasses the following changes: * Define `lit_tools_dir` for flang's test configuration * Replace `(<command> || true)` idiom with `not <command>` * Add `REQUIRES: shell` on tests that invoke a shell script Reviewed By: awarzynski Differential Revision: https://reviews.llvm.org/D89368

[flang] Initialize PRINT semantics. Fixes flang-compiler/f18#516 (flang-compiler/f18#528) There are no Clause 12 constraints to check for PRINT, but PRINT does share FMT specifier processing with READ and WRITE. To avoid interactions between these I/O statements, reset IoChecker values for PRINT.

[flang] Check that various variables referenced in I/O statements may be defined A number of I/O syntax rules involve variables that will be written to, and must therefore be definable. This includes internal file variables, IOSTAT= and IOMSG= specifiers, most INQUIRE statement specifiers, a few other specifiers, and input variables. This patch checks for these violations, and implements several additional I/O TODO constraint checks. Differential Revision: https://reviews.llvm.org/D86557

[flang] Semantic checks for bad usage of whole assumed-size arrays The semantics pass currently checks for several constraints that apply to the use of whole assumed-size arrays in various contexts, but C1002 wasn't really implemented. This patch implements C1002 by disallowing the use of whole assumed-size arrays in expressions and variables unless specifically allowed by the context. This centralizes the error reporting, which has been improved with a link to the array's declaration. Differential revision: https://reviews.llvm.org/D88691
