[ConstantFolding] Non-constrained functions in strictfp
Non-constrained function calls, allowed in strictfp functions by
PR188297, are equivalent to their constrained counterparts with dynamic
rounding and strict exception handling. When constant folding the calls
of these functions, some cases cannot be folded due to unknown rounding
mode or floting-point exceptions that can be lost. This change adapts
constant folding for these case.
[IR] Use iteration limit in stripPointerCastsAndOffsets (#190472)
Using a SmallPtrSet is not quite free for such a frequently called
operation. However, calls on ill-formed IR are not particularly rare, so
some iteration limit is needed. Therefore, use a simple counter.
Termination statistics on a Clang Release build for N>5:
2448 N=6
1295 N=7
480 N=8
294 N=9
160 N=10
14350 (endless loop)
Therefore, bound the number of iterations by 12, which should cover most
practically relevant cases.
It is worth noting that _all_ of the endless loop cases have the

libc: fix undefined behavior in int64_to_float128
When negating a signed integer, the integer must not be LLONG_MIN, as
negating that value would not change the sign. GCC's -ftrapv mode
detects cases like this reliably.
In this case, on sparc64 with -O2 (but not -O0 or -O1),
countLeadingZeros64(LLONG_MIN) returned 48 instead of the desired 0, and
int64_to_float128(LLONG_MIN) returned -0x1p+14 instead of the desired
-0x1p+63.
The same pattern is used in several other conversion functions. These
will be fixed in a follow-up commit once the lint tests for msg_380 and
msg_381 on sparc64 work again.
