[ubsan] Fix numerical overflows in the compiler
...
Mostly signed integer overflows, and a few cases of double
division by zero (which is defined by IEEE-754 to return
Infinity (or NaN for 0/0) but is UB in C++).

[turbofan] PersistentMap: Allow hash values larger than 32bit and some cleanup
...
This works around a bug in the libc++ implementation of bitset
(https://bugs.llvm.org/show_bug.cgi?id=35438 ) resulting in high
bits outside the bitset leaking through, breaking the ordering
invariant of PersistentMap::iterator. This did not surface so far
because the hash values used in escape analysis so far all only used
32 bits.
