Even in the restricted config, we can still end up having to print
certain non-allocatable registers, e.g. if required by a FIXED_REGISTER

Introduce a CompilationDependency that let's us optimize the lookup of
a function's "prototype" property. This is basically the same as
InitialMapDependency, except that if the function's initial map doesn't
exist yet, it is created after compilation.

Some builtins, so-called wasm runtime stubs, are copied off-heap to
ensure reachability through near jumps. These builtins must be
individually position-independent. In particular, they may not contain
pc-relative calls to other builtins.

Drive-by: Set hard_abort mode for all wasm runtime stubs to avoid Abort
calls.

This call can be used by embedder to request a GC for testing reasons.
The GC also takes the current embedder stack state as an argument that
is forwarded to the embedder when entering the atomic pause.

This way embedders can request garbage collections for testing and set
how the embedder should treat the stack.

Refactor the ArrayIteratorPrototypeNext CSA builtin to handle the
JSArray element access in a dedicated helper macro, very similar
to how it's done for JSTypedArray's. Also add support for dictionary
elements to this helper macro using the existing dictionary access
logic in the CodeStubAssembler.

This improves the readability of the builtin significantly and the
performance of iterating arrays with dictionary elements goes up by
a factor of ~3.5x.

This patch splits the log file into a vector of std::strings when
logging is stopped, so verifying that lines are present can be done in
terms of std library functions. Verifications are now done by simple
substring matching instead of via a prefix or suffix, in preparation for
a new test that needs to match the middle of a line.

This patch also deletes some dead/debugging code.

Inspector tries to provide sourceURL and sourceMappingURL for scripts
with parser errors. Without this CL we convert source of each script
to inspector string and search for magic comment there. Some web sites
use pattern when they get some data from network and constantly try to
parse this data as JSON, in this case we do a lot of useless work.

So we can parse magic comments on V8 side only for compilation errors
(excluding parse JSON errors), to do it we can reuse scanner by running
it on each potential comment.
