971468031a Use toString tag to format receiver in stack traces
This concerns formatting of calls to, e.g., Math.acos in stack traces,
in which the receiver is an object with an attached toString tag. If
such a tag exists, use it to format the receiver typename to ensure that
the stack trace includes 'Math.acos' instead of 'Object.acos'.

f59a23356b [builtins] Add receiver to builtin exit frames
Stack trace generation requires access to the receiver; and while the
receiver is already on the stack, we cannot determine its position
during stack trace generation (it's stored in argv[0], and argc is only
stored in a callee-saved register).

This patch grants access to the receiver by pushing argc onto builtin
exit frames as an extra argument. Compared to simply pushing the
receiver, this requires an additional dereference during stack trace
generation, but one fewer during builtin calls.

5febc27b5d [builtins] New frame type for exits to C++ builtins
Prior to this commit, calls to C++ builtins created standard exit
frames, which are skipped when constructing JS stack traces. In order to
show these calls on traces, we introduce a new builtin exit frame type.

Builtin exit frames contain target and new.target on the stack and are
not skipped during stack trace construction.

f47b9e9810 [builtins] Introduce a proper BUILTIN frame type.
This adds a new BUILTIN frame type, which supports variable number of
arguments for builtins implemented in hand-written native code (we will
extend this mechanism to TurboFan builtins at some point). Convert the
Math.max and Math.min builtins to construct a BUILTIN frame if required.

This does not yet work for C++ builtins, but that'll be the next step.
