Add an additional argument to the base implementation of KernelBytecodeDisassembler::Disassemble that is the base address to use
when FLAG_disassemble_relative is enabled.
For the delegating versions of KernelBytecodeDisassembler::Disassemble
that take a Bytecode object, the payload start of the bytecode object
is retrieved and used as the base.
For the delegating versions of KernelBytecodeDisassembler::Disassemble
that take neither a base or a bytecode object, the start is used as
the base.
When tracing instructions in the interpreter, the bytecode is retrieved
via the frame pointer and then its payload start is passed in as the
base, so that the relative offset printed with the instructions match
the relative offsets printed when dumping function bytecode.
TEST=manual use of --disassemble-relative while tracing/dumping bytecode
