Automatically call whatthefailure from assert.soon and friends

Add logic to assert.soon to automatically call hang-analysis prior to throwing.

Add an additional optional parameter to assert.soon which is additional params to pass to hang-analysis js function.

For now do this in addition to throwing such that hang-analysis is just a fancy new bonus-feature. Need to do this while some users of assert.soon are using assert.soon as a retry mechanism. A separate ticket will fix all callers of assert.soon
