Akim Demaille 42fe808292 glr2.cc: run the glr-regression tests ...

When installed on master as of 2020-12-05 (on top of "glr2.cc: fix
when the stack is not expandable", almost all the GLR regression tests
fail (with a SEGV):

    709: Badly Collapsed GLR States: glr2.cc             FAILED (glr-regression.at:130)
    712: Improper handling of embedded actions and dollar(-N) in GLR parsers: glr2.cc FAILED (glr-regression.at:275)
    715: Improper merging of GLR delayed action sets: glr2.cc FAILED (glr-regression.at:404)
    718: Duplicate representation of merged trees: glr2.cc FAILED (glr-regression.at:502)
    721: User destructor for unresolved GLR semantic value: glr2.cc FAILED (glr-regression.at:566)
    724: User destructor after an error during a split parse: glr2.cc FAILED (glr-regression.at:624)
    727: Duplicated user destructor for lookahead: glr2.cc FAILED (glr-regression.at:724)
    730: Incorrectly initialized location for empty right-hand side in GLR: glr2.cc FAILED (glr-regression.at:823)
    733: No users destructors if stack 0 deleted: glr2.cc FAILED (glr-regression.at:911)
    736: Corrupted semantic options if user action cuts parse: glr2.cc FAILED (glr-regression.at:974)
    739: Undesirable destructors if user action cuts parse: glr2.cc FAILED (glr-regression.at:1042)
    742: Leaked semantic values if user action cuts parse: glr2.cc FAILED (glr-regression.at:1173)
    748: Incorrect lookahead during nondeterministic GLR: glr2.cc FAILED (glr-regression.at:1546)
    751: Leaked semantic values when reporting ambiguity: glr2.cc FAILED (glr-regression.at:1639)
    754: Leaked lookahead after nondeterministic parse syntax error: glr2.cc FAILED (glr-regression.at:1710)
    757: Uninitialized location when reporting ambiguity: glr2.cc FAILED (glr-regression.at:1794)
    766: Predicates: glr2.cc                             FAILED (glr-regression.at:2045)

These pass:

    745: Incorrect lookahead during deterministic GLR: glr2.cc ok
    760: Missed %merge type warnings when LHS type is declared later: glr2.cc ok
    763: Ambiguity reports: glr2.cc ok

With Valentin Tolmer's "glr2.cc: Fix memory corruption bug" commit,
these test fail "gracefully":

    712: Improper handling of embedded actions and dollar(-N) in GLR parsers: glr2.cc FAILED (glr-regression.at:268)
    730: Incorrectly initialized location for empty right-hand side in GLR: glr2.cc FAILED (glr-regression.at:816)
    748: Incorrect lookahead during nondeterministic GLR: glr2.cc FAILED (glr-regression.at:1539)

And these do not end:

    709: Badly Collapsed GLR States: glr2.cc             FAILED (glr-regression.at:123)
    715: Improper merging of GLR delayed action sets: glr2.cc FAILED (glr-regression.at:397)
    718: Duplicate representation of merged trees: glr2.cc FAILED (glr-regression.at:495)
    751: Leaked semantic values when reporting ambiguity: glr2.cc FAILED (glr-regression.at:1632)

With "tests: glr2.cc: run the glr-regression tests", none loop, and
709, 715, and 751 pass.  Only 718 still fails.

* tests/glr-regression.at: Run all the tests with glr2.cc.
* tests/local.at (AT_GLR2_CC_IF): New.
