This patch moves the desugaring from the parser to the bytecode generator for super calls that have a spread at a non last position. This allows us to have the post super() call behavior, such as initializing instance fields in one place in VisitCallSuper.

Looking up line numbers with the JITLineInfoTable would sometimes give wrong answers. Fix these bugs and add a cctest for this data structure. Also do some cleanup while we're here like inlining the (empty) constructor and destructor and removing the empty() method which is only used unnecessarily anyway, to make the contract of GetSourceLineNumber a bit clearer. Also rename the data structure to SourcePositionTable, because it doesn't just provide info for JIT code, but also bytecode, and 'Info' is pretty ambiguous.

Memory size, mask and function table size are 32-bit values in wasm. There is no relation to pointer size. Hence, replace uintptr_t by uint32_t. These fields are already being loaded as uint32_t in wasm-compiler.cc, causing problems on big endian systems.
