test: make ValueTest/objects float check robust against x87 excess precision (#1700)

ValueTest/objects stores the float literal 0.12345f into a Json::Value
(widened to the stored double) and then asserts equality against the
original 0.12345f. On 32-bit x86 targets where GCC defaults to x87 math
(-mfpmath=387, 80-bit excess precision) and the baseline lacks SSE2, the
round-trip yields the exact double 0.12345 rather than the float-widened
0.12345000356435776, so the exact double comparison fails even though the
library itself is correct.

Compare the stored value narrowed back to float via asFloat(): both the
expected literal and asFloat() collapse to the same float value on every
architecture, keeping the numeric round-trip check while making it
precision-robust.
