The libc implementation newlib defines these symbols and causes a compiler error. Per the standard (ISO 9899:1999 reserved identifiers section), any identifier beginning with two underscores or an underscore and a capital letter is reserved for libc. The definitions are not used anywhere in the source code either.

The load_regs assembly function uses its caller's frame pointer.
C/C++ compilers are allowed to make optimizations to their
representation of the stack, and frequently omit the frame pointer.
The functions _EEXIT in t_instructions.cpp and _SE3 in
u_instructions.cpp both call load_regs, and thus should be the only ones
that should be affected by deoptimization.
Even -O0 may omit the frame pointer (indeed we found this to be the case
when compiling with GCC 7.3.0), so this change also makes that requirement
explicit by by means of -fno-omit-frame-pointer.
The analogous attribute for -fno-omit-frame-pointer is not available in
clang, so the clang version of the LOAD_REGS_ATTRIBUTES is simply
[[clang:optnone]].
An added bonus of switching the -O0 flag over to an attribute in source
code is that alternate build tools are easier to port to :)

Document that _mm_pause definition requires -ffreestanding.
Guard the definition of __STDC_FORMAT_MACROS with #ifndef/#endif.

The C_OBJS is forgotten to link OBJS togeter in Makefile.
