The RVCT compiler may emit calls to the various __aeabi_c?cmp??
functions, which return their results via the CPU condition flags
C and Z. According to ARM doc IHI 0043D 'Run-time ABI for the ARM
architecture':
The 3-way comparison functions c*cmple, c*cmpeq and c*rcmple return
their results in the CPSR Z and C flags. C is clear only if the operands
are ordered and the first operand is less than the second. Z is set only
when the operands are ordered and equal.
Add implementations for the double and float variants of the above.
