In bug 1492064 glandium disabled the Baseline JIT when we don't have FP support. 

Baseline initially supported non-SSE2 hardware because it was still pretty common 5-6 years ago, but our official builds now require SSE2 (although some downstreams don't). Now that we disable both JITs we can remove the more fine-grained jitSupportsFloatingPoint checks in Baseline and CacheIR code.
