Factor the generation of the (integral) tables bw yacc.c and lalr1.cc.
Get rid of (yy)rhs and (yy)prhs.
These tables are no longer needed in the parsers, and they don't seem to
be useful. They are not documented either.

Adjust the computation of (yy)r2.
Get rid of lalr1-split.cc.
It was no longer maintainer.

Adjust.
Prefer TESTSUITE_FLAGS.
TESTSUITEFLAGS is barely readable.

for backward compatibility.
Use the former instead of the latter.

Get rid of yyrhs and yyprhs in yacc.c.
- They were used to get the symbol types, given a rule number, when
- displaying the top of the stack before a reduction. But the symbol type
- is available from the state stack. This has two be benefits: two tables
- less in the parser (making it smaller), and a more consistent use of the
- three stacks which will help to fuse them.
