In Module_1,

	Criticality ::= ENUMERATED { reject, ignore, notify }

In Module_2,

	IMPORTS
		Criticality
	FROM Module_1

		someMessage SOME-CLASS ::= {
			CRITICALITY	ignore
		}

This pull request add the capability to resolve 'reject', 'ignore' and 'notify'
in Module_2.

The aforementioned error message displayed during processing the following ASN.1 excerpt.

S1AP-ELEMENTARY-PROCEDURES S1AP-ELEMENTARY-PROCEDURE ::= {
    S1AP-ELEMENTARY-PROCEDURES-CLASS-1 |
    S1AP-ELEMENTARY-PROCEDURES-CLASS-2,

Because S1AP-ELEMENTARY-PROCEDURES-CLASS-1 and S1AP-ELEMENTARY-PROCEDURES-CLASS-2
are resolved 'after' S1AP-ELEMENTARY-PROCEDURES, so the ioc tables of them are not
available during resolving S1AP-ELEMENTARY-PROCEDURES. So we can not drop the
latter's containedSubtype field at first pass of asn1f_resolve_constraints of fix
process.

We also add second pass of asn1f_resolve_constraints to have a chance to combine
ioc tables of S1AP-ELEMENTARY-PROCEDURES-CLASS-1 and
S1AP-ELEMENTARY-PROCEDURES-CLASS-2.

From `man bash`
The return status of a pipeline is the exit status of the last command, unless the pipefail option is enabled.  If pipefail is enabled, the
pipeline's return status is the value of the last (rightmost) command to exit with a non-zero status, or zero if all commands exit success‐
fully.

- Do not tail the check output as the test log is now written in
  test-suit.log files
- On failure display the whole content of every test-suite.log file found
  in the build directory and exit with 1
