v8/test/cctest/interpreter/bytecode_expectations/Modules.golden
Ross McIlroy c68df4110d [Interpreter] Allocate context registers as temporary registers. 
Rather than trying to pre-calculate the number of contexts required during
scope analysis, instead just allocate context registers in the register
allocator. This reduces frame size a bit due to reusing of registers when
the context isn't pushed.
