* src/vm/jit/arm/codegen.c: Remove hack for return value in float registers.

This would only be relevant for -mfloat-abi=hard (armhf). At the moment,
support for armhf is rather pointless and can never have worked because all
arguments are passed in integer registers unconditionally. This applies to both
the internal and the system ABI.
