a698d3d579 [flang] Changes responding to comments on my previous pull request. Specifically -- 
parse-tree.cc
 - Cleaned up the use of "const" in several declarations.
check-do-stmt.cc
 - Replaced uses of parser::Messages with SemanticsContext.
 - Removed unused "==" operator from the DoStmtContext class.
 - Reduced the size of the GetBounds function by calling GetLoopControl().
 - Changed the warning message for REAL DO controls to not mention standard
   extensions.
check-do-stmt.h
 - Restored the forward reference to Fortran::parser::DoConstruct and removed
   the include of parse-tree.h
dosemantics*.f90
 - Removed extraneous references to the "RUN" command.
test_errors.sh
 - Simplified and generalized the extraction of the OPTIONS specification.

93a59505a5 [flang] These changes are for issue 458, to perform semantic checks on DO variable 
and initial, final, and step expressions.  As a new extension, we want to allow
REAL and DOUBLE PRECISION values for them by default.

Here's a summary of the changes:
 - There already existed infrastructure for semantic checking of DO loops that
   was partially specific to DO CONCURRENT loops.  Because I re-used some of
   this infrastructure, I renamed some files and classes from "concurrent" to
   "stmt".
 - I added some functions to distinguish among the different kinds of DO
   statements.
 - I added the functions to check-do-stmt.cc to produce the necessary warnins
   and errors.  Note that there are no tests for the warnings since the
   necessary testing infrastructure does not yet exist.
 - I changed test-errors.sh so that additional compilation options can be
   specified in the test source.
 - I added two new tests to test for the various kinds of values that can be
   used for the DO variables and control expressions.  The two tests are
   identical except for the use of different compilation options.
   dosemantics03.f90 specifies the options "-Mstandard -Werror" to produce
   error messages for the use of REAL and DOUBLE PRECISION DO variables and
   controls.  dosemantics04.f90 uses the default options and only produces
   error messages for contructs that are erroneous by default.

e69c6a6259 [flang] Fix issue flang-compiler/f18#486 
In a function without a function result specified, the name in the
`FunctionStmt` was resolved to the function result symbol rather than
the function symbol itself. That is inconsistent with subroutines and
other functions.

The fix is to explicitly set the function name symbol after the result
has been resolved.
