The problem here is we are trying to add 1 to a -1 in a signed 1-bit
field and coming up with UNDEFINED because of the overflow.
Signed 1-bits are annoying because you can't really add or subtract
one, because the one is unrepresentable. For invert() we have a
special subtract_one() function that handles 1-bit signed fields.
This patch implements the analogous add_one() function so that invert
works.

this patch implements thre two-state optimize_for_size predicates, so with -Os
and with profile feedback for never executed code it returns OPTIMIZE_SIZE_MAX
while in cases we decide to optimize for size based on branch prediction logic
it return OPTIMIZE_SIZE_BALLANCED.
The idea is that for places where we guess that code is unlikely we do not
want to do extreme optimizations for size that leads to many fold slowdowns
(using idiv rather than few shigts or using rep based inlined stringops).
I will update RTL handling code to also support this with BB granuality (which
we don't currently). LLVM has -Os and -Oz levels where -Oz is our -Os and
LLVM's -Os would ocrrespond to OPTIMIZE_SIZE_BALLANCED. I wonder if we want
to export this to command line somehow? For me it would be definitly useful
to test things, I am not sure how "weaker" -Os is desired in practice.

This patch fixes the ICE in the PR by bailing out of find_bswap_or_nop

it's the most appropriate place to reject them
here rather than in the callers.

This makes us always use a single-bit boolean type component type

the inconsistencies from the translation requirement now that
