big ints: setTwosCompIntLimit
...
This function can be used to initialize a big integer to either the upper
or lower limit of a 2s-complement integer. Note that the result is still
in sign-magnitude representation, though in order to convert it into twos
complement all one has to do is take the absolute value.

big ints: split lladd/llsub into carry variants
...
lladd is now implemented in terms of lladdcarry, which returns the carry limb.
Similarly, llsub is implemented using llsubcarry, which returns the borrow limb.

C backend: improved Decl name lowering
...
Decl names are now rendered fully qualified, so that e.g. "main" in two
different files does not conflict with each other.
Additionally, they are now mangled so as to not generate invalid C
identifier names.

AstGen: fix while and for with unreachable bodies

Companion commit to 61a53a587558ff1fe1b0ec98bb424022885edccf.
This commit also moves over a bunch of behavior test cases to the
passing-for-stage2 section.

AstGen: fix if, orelse, catch, with unreachable bodies
...
Before, the system to replace a result location pointer with a
traditional break instruction did not notice the case when one of the
bodies was unreachable. Now, the emitted ZIR code is improved and
simplified in this case, resulting in a new passing behavior test.
