 testsuite: Fix a variety of issues when building with integer-simple

  * Mark arith011 as broken with integer-simple

    As noted in #16091, arith011 fails when run against integer-simple with
 a
    "divide by zero" exception. This suggests that integer-gmp and integer-
 simple
    are handling division by zero differently.

  * This also fixes broken_without_gmp; the lack of types made the previous
    failure silent, sadly. Improves situation of #16043.

  * Mark several tests implicitly depending upon integer-gmp as broken
    with integer-simple. These expect to see Core coming from integer-gmp,
    which breaks with integer-simple.

  * Increase runtime timeout multiplier of T11627a with integer-simple

    I previously saw that T11627a timed out in all profiling ways when run
 against
    integer-simple. I suspect this is due to integer-simple's rather
 verbose heap
    representation. Let's see whether increasing the runtime timeout helps.

    Fixes test for #11627.

 This is all in service of fixing #16043.
