Bug#45288: pb2 returns a lot of compilation warnings
Fix assorted warnings that are generated in optimized builds.
Most of it is silencing variables that are set but unused.
This patch also introduces the MY_ASSERT_UNREACHABLE macro
which helps the compiler to deduce that a certain piece of
code is unreachable.
include/my_compiler.h:
Use GCC's __builtin_unreachable if available. It allows
GCC to deduce the unreachability of certain code paths,
thus avoiding warnings that, for example, accused that a
variable could be used without being initialized (due to
unreachable code paths).
