Looks like they got disabled for some reason when the 1.0.3 update landed. Try confirms that they're still green, so let's get them turned back on before that has a chance to change. https://treeherder.mozilla.org/#/jobs?repo=try&revision=8de0bbd59a1a3ca6267fe3e108a4e4e0a98702a4&exclusion_profile=false FWIW, M-e10s(gl) on Ash has already caught crashes and leaks that weren't being seen elsewhere, so there is value to running these tests under e10s mode as well as non-e10s.

Looks like test_conformance__textures__texture-size-limit.html needs to be explicitly skipped on ASAN as well due to frequently timing out (given the pre-existing fail-if annotation for Linux, I guess it's expected for that test to be flaky).

This makes ASAN a lot happier. While I was at it, I cleaned up a couple other annotations to be a bit more specific. Confirmed green on Try (the infra failures were because I had to tweak the buildbot max runtime for the e10s jobs and some of the slaves started running tests before picking up the newer value). https://treeherder.mozilla.org/#/jobs?repo=try&revision=a2434c5809ea227a0afb89b4edfe426f3d2bbb64&exclusion_profile=false&group_state=expanded
