Liveedit step-by-step: 1. calculate diff between old source and new source, 2. map function literals from old source to new source, 3. create new script for new_source, 4. mark literals with changed code as changed, all others as unchanged, 5. check that for changed literals there are no: - running generators in the heap, - non droppable frames (e.g. running generator) above them on stack. 6. mark the bottom most frame with changed function as scheduled for restart if any. 7. for unchanged functions: - deoptimize, - remove from cache, - update source positions, - move to new script, - reset feedback information and preparsed scope information if any, - replace any sfi in constant pool with changed one if any. 8. for changed functions: - deoptimize - remove from cache, - reset feedback information, - update all links from js functions to old shared with new one. 9. swap scripts.

When parsing a numeric literal in a line like "a=0x0e+b|0;", currently the scanner consumes the "e+" part (as it thinks it's the start of an exponent). In the ECMAScript lexical grammar HexIntegerLiteral cannot contain exponents, which means the '+' character should be parsed as a binary operator.

Adds a instance types for each HashTable subtype, rather than reusing HASH_TABLE_TYPE. This allows us to check for these types by checking the instance type directly, rather than by comparing against the map in the root set. Also, as a drive-by, do the same for SCRIPT_CONTEXT_TABLE_TYPE, and use instance type checks rather than map checks for Context types. This is a good general clean-up, but in particular is intended for GetIsolate removal.

This change helps mostly to reduce register pressure. By default, we compile LoadStackPointer into a move from the stack register into some general purpose register and then later use that register. This might trigger a spill to free up space, which is particularly costly in loops.

Liftoff needs to emit the same code, thus move it to a place where it can be reused. Also, switch the _MSC_VER switch to V8_OS_WIN. It is unclear if _MSC_VER would also be set in clang. V8_OS_WIN seems to fit better. Drive-by: Reorder the code to save one jmp in the loop (loop inversion).
