The (32 - fraction_bits) value should be encoded so that the least
significant bit is set to bit 5 and the four next bits to bits 0-3. Fix
the previously incorrect encoding. This bug did not cause behavioral
issues before, since in existing uses of the function the order of the
bits in the immediate value does not matter, as they are all 1.

Instread of using the transition array map to store the iteration index, we are using the constructor field of the map. Moreover, I removed the unchecked transition array accessors.

Function calls are handled with a LoadIC and a FunctionCallStub. This works well, but we can create a platform to gather custom feedback by inventing a CallIC. CallIC takes a JSFunction as input, maintains UNINIT/MONO/MEGA state in a feedback slot, and engages in limited patching for the most efficient code.

The change creates a degrade in NBody tests, but a follow-on CL addresses it by using this custom feedback platform to give a 45% improvement.
