PR modula2/102344 TestLong4.mod FAILs

This is a testsuite fix for TestLong4.mod so that it
succeeds on 32 bit systems.  The original TestLong4.mod has
been rewritten as testing MAX(LONGCARD) into the variable l.
The new testlong4.mod has been added to cpp/pass.  The new
testcode uses the C preprocessor to select the appropriate
constant literal depending upon __SIZEOF_LONG__.

gcc/testsuite/ChangeLog:

	PR modula2/102344
	* gm2/pim/pass/TestLong4.mod: Rewrite.
	* gm2/cpp/pass/testlong4.mod: New test.
