threadStackOverflow: check whether stack squeezing released some stack (#3677)

In a stack overflow situation, stack squeezing may reduce the stack
size, but we don't know whether it has been reduced enough for the
stack check to succeed if we try again.  Fortunately stack squeezing
is idempotent, so all we need to do is record whether *any* squeezing
happened.  If we are at the stack's absolute -K limit, and stack
squeezing happened, then we try running the thread again.

We also want to avoid enlarging the stack if squeezing has already
released some of it.  However, we don't want to get into a
pathalogical situation where a thread has a nearly full stack (near
its current limit, but not near the absolute -K limit), keeps
allocating a little bit, squeezing removes a little bit, and then it
runs again.  So to avoid this, if we squeezed *and* there is still
less than BLOCK_SIZE_W words free, then we enlarge the stack anyway.

Implement -fexpose-all-unfoldings, and fix a non-termination bug

The -fexpose-all-unfoldings flag arranges to put unfoldings for *everything*
in the interface file.  Of course,  this makes the file a lot bigger, but
it also makes it complete, and that's great for supercompilation; or indeed
any whole-program work.

Consequences:
  * Interface files need to record loop-breaker-hood.  (Previously,
    loop breakers were never exposed, so that info wasn't necessary.)
    Hence a small interface file format change.

  * When inlining, must check loop-breaker-hood. (Previously, loop
    breakers didn't have an unfolding at all, so no need to check.)

  * Ditto in exprIsConApp_maybe.  Roman actually tripped this bug,
    because a DFun, which had an unfolding, was also a loop breaker

  * TidyPgm.tidyIdInfo must be careful to preserve loop-breaker-hood

So Id.idUnfolding checks for loop-breaker-hood and returns NoUnfolding
if so. When you want the unfolding regardless of loop-breaker-hood,
use Id.realIdUnfolding.

I have not documented the flag yet, because it's experimental.  Nor
have I tested it thoroughly.  But with the flag off (the normal case)
everything should work.
