testsuite: Fix a variety of issues when building with integer-simple
- Mark arith011 as broken with integer-simple
As noted in Trac #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 Trac #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 Trac #11627.
This is all in service of fixing Trac #16043.
