Used incorrect register for referencing RegExp data, so it always failed to match the fast case. When modifiying the object layout, it was possible to make it crash instead.

Ensure that there is always enough bytes between consequtive calls in unoptimized code to write a call instruction at the return points without overlapping. This handles the case where two return points were only four bytes apart (because the latter call was to a register).

Now mark SetElement as must use result The debugger runs inside its own context so there should be no setters hit. Which is the reason for the live-edit code asserting non-empty handles.

This change splits the existing phi elimination into two phases: 1. Remove redundant phis 2. Remove dead phis with a fixed point iteration. The new approach allows us to remove dead phis that are connected in a cycle.

Move strict mode flag from TemporaryScope to Scope so that it can be accessed from variable binding code. Arguments do not alias in strict mode (ia32, x64 and arm, codegen and full codegen). Hydrogen tolerates null arguments_shadow(). In codegen-<arch> arguments object is allocated eagerly to capture values before they get modified.

Function inlining no longer uses subgraphs. We detect inlining in an effect context and avoid materializing a return value earlier than we did before.

Change the way we construct the graph for polymorphic loads to match that of polymorphic stores. Introduce a stack-allocated helper for saving and restoring all the function-specific graph builder state that needs to change when we begin translating an inlined function. Make this class authoritative by moving redundant state out of the builder and deferring to the current function's state. Ensure that we always print a tracing message when abandoning an inlining attempt.

Move the value of the root-array register to offset 128 from the start of the root array. This allows indices 16..31 to be reached using only an 8-bit displacement, saving three bytes per access.

They do not use subgraphs or subgraph scopes. Instead of computing a list of single-block subgraphs and then adding all the edges afterward, build both the blocks and edges directly.
