Peter Steinfeld 93ee588232 [flang] Rename the runtime routine that reports a fatal user error
As per Steve Scalpone's suggestion, I've renamed the runtime routine to
better evoke its purpose.

I implemented a routine called "Crash" and added a test.

Jean Perier 7796d81ae8 [flang] Skip `Fortran STOP:` before message when NO_STOP_MESSAGE is set
In 'STOP bye bye', do not print 'Fortran STOP:` before 'bye bye' when
NO_STOP_MESSAGE environment variable is set at runtime.

Also only exit with code 1 in StopStatementText if this is an ERROR STOP.
This matches other compiler behaviors.

Move STOP related unit tests in their own test file and add new tests to
cover this change.

Peter Klausler 4a0af824ee [flang] Respect NO_STOP_MESSAGE=1 in runtime
When an environment variable NO_STOP_MESSAGE=1 is set,
assume that STOP statements with a successful code
have QUIET=.TRUE.

Peter Klausler 830c0b9023 [flang] Move runtime API headers to flang/include/flang/Runtime
Move the closure of the subset of flang/runtime/*.h header files that
are referenced by source files outside flang/runtime (apart from unit tests)
into a new directory (flang/include/flang/Runtime) so that relative
include paths into ../runtime need not be used.

flang/runtime/pgmath.h.inc is moved to flang/include/flang/Evaluate;
it's not used by the runtime.
