tools/nolibc: add tests for the integer limits in stdint.h
This commit adds tests for the limits added in a previous commit. The
limits are defined in decimal in stdint.h and as hexadecimal in the
tests (e.g. 0x7f = 127 or 0x80 = -128). Hopefully it catches some of the
most egregious mistakes.
As we rely on the compiler to provide __SIZEOF_LONG__, we also test
whether it is defined.
