This extracts the logic previously inside gen_putobject to a more
reusable helper method jit_putobject.
The motivation for this is that it both simplifies the implementation of
other instructions, and other instructions can reuse the optimized
behaviour for 32-bit special constants (most importantly
opt_getinlinecache).
This commit also expands the optimization to use a mov directly to
memory when we encounter a 32-bit immediate constant. Previously it
covered fixnums and Qtrue/Qfalse, now it will cover any SPECIAL_CONST_P
value which can be represented as a 32-bit immediate. Notably, this
includes static symbols, and Qnil.
