Adds a minimum estimated size.
Data suggests that estimated instruction size (+ relocation info size)
is linear to bytecode array length. This CL adds a constant for this
equation. The ratio remains the same.
This is important, because we want to increase success rate of
estimation when compiling on-heap.
When off-heap, we round up the assembler buffer to 4kB, so this CL
will only impact JS functions with more than 585 bytecodes, i.e, the
new added constant will be negligible.
Note: Relocation info (for Sparkplug) is usually so small that it is
not useful to have a separate zone for this.
