Select verbosity with "make VERBOSE=n". Options so far:
 n=0: No per-test output
 n=1: Only failing test results
 n=2: As above, plus progress information (names of all tests)
 n=3: As aobve, plus commands called.
Default currently is n=3, although n=2 might be a nicer default.

Accidentally broken by my last commit

As a side-effect, the new `{-# MINIMAL #-}` facility (see #7633) changes
the existing separate warnings for each missing method declaration:

{{{
No explicit method or default declaration for ‛+’
In the instance declaration for ‛Num T’
}}}

to a single warning per class of the following form:

{{{
No explicit implementation for
  ‛+’, ‛*’, ‛abs’, ‛signum’, and ‛fromInteger’
In the instance declaration for ‛Num T’
}}}

This commit adapts the reference output files in the testsuite to follow
this change in GHC's warnings messages.

But seems to be fixed in head already.

Expand 'bytes allocated' allowed in haddock.base, and update error
messages.

This closes #3389, and makes the testsuite go through again.

Added a new test Makefile variable $(dllext), which is
instantiated to .dll or .so or .dylib depending on your platform.

This includes:

 * Adding a test for bswap16 with a low byte >= 128
 * Also test the byteSwapN functions from GHC.Word, tested both INLINE
   and not INLINE, so we test both independent parts: the compilation of
   base, and the backend compiling the code *using* base.
 * Fix the usage of byteSwapN# primitives in the test, by masking off
 * the higher bits when storing the results in Word16/Word32.

Thanks to Reid Barton for the investigation.

Essentially the same tests as for the existing ByteArray# ones.

This test is a bit speculative, because I can't reproduce problem
on my machine. Still, it should work because it produces the same
Cmm that originally caused the problem.
