Message:

Avoid reinterpret_cast alignment increase warnings with GCC on CPU(RISCV64)
​https://bugs.webkit.org/show_bug.cgi?id=228818

Patch by Zan Dobersek <​zdobersek@igalia.com> on 2021-08-05
Reviewed by Adrian Perez de Castro.

• wtf/StdLibExtras.h: As with 32-bit ARM and MIPS targets, RISC-V 64-bit

builds with GCC also spawn warnings when the use of reinterpret_cast
causes an increase in alignment. Workaround via reinterpret_cast_ptr is
thus required for CPU(RISCV64).
