    testsuite: remove Wstrict-overflow related tests

    The following testsuite PRs are related to the now obsolete
    Wstrict-overflow option:

    - Bug 36227 - [4.3 Regression] POINTER_PLUS folding introduces undefined
      overflow
    - Bug 48022 - [4.6 Regression] -Wstrict-overflow warning on code that
      doesn't have overflows
    - Bug 49705 - -Wstrict-overflow should not diagnose unevaluated
      expressions
    - Bug 52904 - -Wstrict-overflow false alarm with bounded loop

    They are exercising code that no longer exists, so remove all of them.
    Two other tests (pr81592.c and pragma-diag-3.c) have Wstrict-overflow
    checks that got removed.

    gcc/testsuite/ChangeLog:

            * gcc.dg/pr81592.c: Removed strict-overflow options.
            * gcc.dg/pragma-diag-3.c: Removed Wstrict-overflow option, along
            with a reference and tests for PR66098 ("[5 regression] #pragma
            diagnostic 'ignored' not fullyundone by pop for
            strict-overflow").
            * gcc.dg/pr36227.c: Removed.
            * gcc.dg/pr48022-1.c: Removed.
            * gcc.dg/pr48022-2.c: Removed.
            * gcc.dg/pr49705.c: Removed.
            * gcc.dg/pr52904.c: Removed.
