Improve setjmp()/longjmp() performance.
...
Exception handling for the C backend used setjmp()/longjmp()
unconditionally. However, on POSIX systems, these functions save and
restore the signal mask, adding considerable overhead to exception
handling, even where no exceptions are involved. The compiler and
library now try to use either _setjmp()/_longjmp() or
sigsetjmp()/siglongjmp() where possible, marked by the defines
"nimRawSetjmp" and "nimSigSetjmp", respectively. The define
"nimStdSetjmp" can be used to revert to setjmp()/longjmp() instead.

Avoid unnecessary #include triggered by importc vars.
...
When a C variable or macro is imported via an {.importc.} var or
let statement, but no definition is needed and the variable does
not have an initializer part, then there is also no need to generate
an #include for the associated header until and unless the variable
is actually used. The header is already generated upon use, but
unnecessarily also when the variable is defined.
This is an issue with the posix module in particular, where a lot
of unnecessary header files are being included because relevant
constants are defined via importc vars, and those header files
may not even be available on a given system.
This patch omits the generation of the #include directive for those
definitions where they aren't needed.

The results so far are inconclusive:
The rope cache tries have been reduced by more than 125K (nearly 20%),
but the bootstrap time seems to be ever slightly increasing (0.01s).
