Gaius Mulley 9fadd8dec7 Fixup noreturn attributes in modula-2 [PR108551] and [PR108612] 
PR108612 - m2/gm2-libs-iso/ClientSocket.mod:229:1: error: control
reaches end of non-void function [-Werror=return-type]
PR108551 - gcc/m2/gm2-libs-pim/Termbase.mod:128:1: error: control
reaches end of non-void function [-Werror=return-type]
This patch adds missing return values to the procedure functions
mentioned in PR108612 and PR108551.  It corrects the noreturn
attribute to throw and rethrow in the modula2 frontend.  The patch
also changes HALT, Halt, Raise procedures in the libraries to use
the <* noreturn *> attribute.  Finally the patch includes
rebuilt bootstrap tools mc and pge.
