Auto merge of #49095 - alexcrichton:debug-asmjs, r=kennytm

Try to reduce amount of time on the asmjs builder

This PR has two commits for two separate strategies:

* First it disables optimizations for all tests, hopefully saving time by not optimizing the test code. This caused a number of run-pass tests to fail which are switched to being ignored here.
* Next it disables a number of test suites which aren't asm.js specific and already run elsewhere

cc #48826
