The function had a wrong behaviour expecting `this` value to be a RegExp Object.
However as the standard says `this` value should be an Object, and its `source` and `pattern` values' `toString()`s should be returned in a form of `/<source>/<flags>`.

* Use non-universal compiler options for gcc only
Compiler of macOS (clang) doesn't support all options currently
used. Optimization flags `-frounding-math` and `-fsignaling-nans`
are not supported, while warning options
`-Wno-unused-but-set-variable` and `-Wno-unused-but-set-parameter`
are unknown.

* Remove deprecated register storage class specifier
The storage class specifier `register` was deprecated in C++11 (and
is incompatible with C++17, where the keyword is unused and
reserved).

* Don't use memcpy on PointerValue objects
Class `PointerValue` and its descendants are dynamic classes, their
instances have a vtable pointer. C functions like `memcpy` know
nothing about C++ classes and object memory layouts, so using
C-style memory access to C++ objects with vtable pointers makes the
compiler complain.
This patch replaces `memcpy` with a more C++-ish approach.
