UBSan: Don't diagnose inf/nan conversions between floating-point types. It's far from clear whether these have undefined behavior, and these checks are helping no-one. Keep the double->float overflow warnings, though, since those are useful in practice, even though it's unclear whether such operations have defined behavior.

PR15383: When -fsanitize=float-cast-overflow checks a float-to-int conversion,
it wasn't taking into account that the float should be truncated *before* the
range check happens. Thus (unsigned)-0.99 and (unsigned char)255.9 have defined
behavior and should not be trapped.

[ubsan] Implement the -fcatch-undefined-behavior flag using a trapping
implementation; this is much more inline with the original implementation
(i.e., pre-ubsan) and does not require run-time library support.
The trapping implementation can be invoked using either '-fcatch-undefined-behavior'
or '-fsanitize=undefined-trap -fsanitize-undefined-trap-on-error', with the latter
being preferred. Eventually, the -fcatch-undefined-behavior' flag will be removed.

Scalar shifts in the OpenCL specification (as of v. 1.2) are defined to be
with respect to the lower "left-hand-side bitwidth" bits, even when negative);
see OpenCL spec 6.3j. This patch both implements this behaviour in the code
generator and "constant folding" bits of Sema, and also prevents tests
to detect undefinedness in terms of the weaker C99 or C++ specifications
from being applied.

If we flow off the end of a value-returning function:
- outside C++, return undef (behavior is not undefined unless the value is used)
- in C++, with -fcatch-undefined-behavior, perform an appropriate trap
- in C++, produce an 'unreachable' (behavior is undefined immediately)

-fcatch-undefined-behavior: add the -ftrapv checks to the set of things caught
by this mode, and also check for signed left shift overflow. The rules for the
latter are a little subtle:
* neither C89 nor C++98 specify the behavior of a signed left shift at all
* in C99 and C11, shifting a 1 bit into the sign bit has undefined behavior
* in C++11, with core issue 1457, shifting a 1 bit *out* of the sign bit has
undefined behavior
As of this change, we use the C99 rules for all C language variants, and the
C++11 rules for all C++ language variants. Once we have individual
-fcatch-undefined-behavior= flags, this should be revisited.

New -fcatch-undefined-behavior features:
* when checking that a pointer or reference refers to appropriate storage for a type, also check the alignment and perform a null check
* check that references are bound to appropriate storage
* check that 'this' has appropriate storage in member accesses and member function calls
