[gfortran] Fix PR 19543: Type mismatch when building logical constants

[Tobias Schlüter]

Logical constants were build with type NULL_TREE (i.e. the host's integer
type) which lead to problems when a LOGICAL type wider than int was specified.
 Fixed by this patch, which I will commit as obviously correct along with a
testcase once the testsuite ran successfully.
