deterministic test suite.

Some consistency checks on symbols are performed after all the
symbols were read, by an iteration over the symbol table.  This
traversal is nondeterministic, which can be a problem for test

Avoid this.

Addresses another form of nondeterminism reported by Joel E. Denny.

	* tests/input.at (Numbered tokens): Split the hexadecimal/decimal
	test in two.
	Use different file names for the three tests to make the
	maintenance easier.
