Peter Steinfeld 84b70d8b73 [flang] Enforce constraint C1128 for DO CONCURRENT locality-spec's 
These changes implement most of the requirements for C1128, which says: "A
variable-name that appears in a LOCAL or LOCAL_INIT locality-spec shall not
have the ALLOCATABLE; INTENT (IN); or OPTIONAL attribute; shall not be of
finalizable type; shall not be a nonpointer polymorphic dummy argument; and
shall not be a coarray or an assumed-size array.  A variable-name that is not
permitted to appear in a variable definition context shall not appear in a
LOCAL or LOCAL_INIT locality-spec."

The changes do not implement the checking required to determine whether a
variable can appear in a "variable definition context".

Here's a summary of the changes:
 - I created the function 'PassesLocalityChecks()' to enforce C1128 along with
   C1124, C1125, and C1126.
 - I cleaned up the code to check if a type or symbol is a coarray.
 - I added functions to tools.[h,cc] to test if a symbol is OPTIONAL, INTENT
   IN, finalizable, a coarray, or an assumed size array.  Should these be
   member functions of the type "Symbol"?
 - Since I changed one of the locality related error messages, I needed to
   change the test resolve35.f90.
 - I added the test resolve55.f90 to test all of the checks implemented in this
   update.

Jinxin (Brian) Yang f8da811848 [flang] 2.7.1 DO: Checks about clause arguments that allow Int Expr (flang-compiler/f18#540) 
All the IntExpr argument checks are done through evaluating the result of GetIntValue. If the argument is non-constant integer expr, Expression Analysis will be the gatekeeper.
