Milad Farazmand 1250611b99 PPC/s390: [regexp] Allow JSRegExpResult allocations in large object space 
"Operand(num_saved_registers_)" might be bigger than 16 bits. Using a 32/64 bit load/mov
instruction to overcome the problem.

Port 4c156936e8

Original Commit Message:

    Large regexp results may exceed kMaxRegularHeapObjectSize and must
    thus be allocated in large object space.
