Pete Steinfeld 855f817d9d [flang] More semantic checking for DO constructs 
This time I'm adding to the checks for constraint C1137, which states
that image control statements cannot appear in a DO CONCURRENT.  The
checks I added test to see if the DO CONCURRENT contains an ALLOCATE or
DEALLOCATE that references a coarray.

Pete Steinfeld c3f05ac421 [flang] Added tests for image control statements in DO CONCURRENT 
There was already code in check-do.cc to test for the presence of a
variety of different image control statements, but several of them did
not have associated tests.  This change adds tests for most of them.

Also, I removed the check for the END PROGRAM statement, since its
presence causes a syntax error which prevents the semantic check from
ever being reached.

Tim Keith 3ef61ec226 [flang] Fix tests that use the same .mod file 
The tests run by `test_any.sh` don't redirect their .mod files to
a different directory so they occasionally fail when the same file
is accessed by different tests at the same time. With locking of
module files implemented, this problem reproduces much more reliably

Work around it by changing the module names to be distinct. Also remove
some comments left over when copied from `test_symbols.sh` tests.

Tim Keith 73c630a4ea [flang] Improve module file reading and writing 
Fix problems with writing a mod file while another compilation is
reading or writing. Write to a temp and then rename it:
- compute the new contents of the .mod file
- if it already exists, check if it is already correct
- if not, write new contents to a temp file
- rename the temp to the final destination

`mkstemps()` seems to be the best way to create the temp file.
It returns a file descriptor, so change the rest of the mod file
writing to use POSIX open/read/write/close. This seems to set
errno more reliably too.

There is some extra work around creating the temp to make it have
the same directory and suffix as the final file (so that if one gets
left behind by a crash, "rm *.mod" still cleans it up).
`mkstemps()` creates file with 0600 permissions so try to change it
to what it would have been if we just wrote the file.

Change module file reading to only read the file once; we used to
read it to verify the checksum and then again to parse it.
Instead, change `Parsing` so that we can get the file contents
after `Prescan()` and use that to verify the checksum. Also, it has
a mechanism for searching directories for files, so make use of that
instead of duplicating that functionality in `ModFileReader`.
This requires some changes to how errors are returned so they can
be reported in the right place.
