Access to the constant pool of off-heap builtins must use Instruction{Start,Size} instead of the raw instruction_{start,size} accessors, and we need to copy the constant_pool_offset field when creating trampolines. This in turn required access to the embedded blob without an associated isolate, which is now implemented by global variable set by each isolate. Both writes and reads are relaxed, as races do not matter since each isolate will attempt to set the same value of the blob and its size. Drive-by: Support off-heap code disassembly.
