Bug 1562129 part 2 - Add --blinterp-eager to jit-test 'all' configuration. r=sfink

To not make jstests even slower, this adds --jitflags=jstests and uses it for
jstests in automation. For jstests we can use fewer jit configurations than
for jit-tests.

This also removes the bigint and bigintdebug autospider variants. BigInt is now
enabled by default so we no longer need the configure flag etc.
