This moves regression test that exceed the time limit of their
respective level to the appropriate level. It further updates the
guidelines in the README with information on how to properly categorize
regression tests into levels (with time limits).
Note: Test regress3/issue4717.smt2 was previously unsolved (unknown) and
is now sat (Z3 agrees).

In preparation of removing the old proof module, this commit changes the
regression runner to not add the flag --check-proofs anymore when
running the regressions.

Switches arith_proof.cpp from th_lra to th_lira.
Changes:
Eliminate the d_realMode hack.
instead: modify printOwnedTermAsType prints as integers OR
reals, depending on expectedType.
simultaneously: write printOwnedTermAsType more concisely
also: reimplement printOwnedSort.
Change to the LIRA axioms:
Because they reason about bound types using side conditions, we
no longer need to worry about choosing the correct strictness for
our axiom.
This allows us to cut out a lot of code, rewriting & shrinking
printTheoryLemmaProof.
They also have different names.
This requires us to change a lot of string literals
enable proof-checking for many tests.

This commit removes the SMT1 parser infrastructure and adds the SMT2 translations of the SMT1 regression tests. For now this commit removes regression test regress3/pp-regfile.smt since the SMT2 translation has a file size of 887M (vs. 172K for the SMT1 version).
Fixes #2948 and fixes #1313.

Due to issues in the current proof code, this commit also disables proof
checking for five QF_LRA benchmarks (see issue #2855).

Until now, regression tests were split across tens of different
Makefile.am, which required a lot of code duplication and does not
really seem to be in the spirit of automake. If we want to change the
LOG_COMPILER/LOG_DRIVER for example, we have to change every single
Makefile.am, which is cumbersome (I was able to get something
semi-working by exporting those variables but it didn't seem very
clean). Additionally, it made the output of the regression tests fairly
verbose and split the output across multiple log files. Finally
it also limited parallelism when running the regression tests (this fix lowers
the time it takes to run regression level 1 from 3m to 1m45s on my
machine with 16 threads).
This commit moves all the regression tests into
test/regress/Makefile.tests and changes test/regress/Makefile.am to deal
with this new structure. Finally, it changes how the test summary in
test/Makefile.am is produced: instead of relying on the log files for
the subdirectories, it greps for the test results in the log files of
the individual tests. Not the most elegant solution but we should
probably anyway delegate that task to a Python script at some point.
