[COMPILER_APITEST] Add tests for float to int conversion
These tests come with a VS solution, because that is the only way to test
against a known good system, as the required runtime functions (like _ftol) are
statically linked from the VS runtime library.

+/* Note: There are 2 behaviors for float to unsigned integer conversion:
+ * 1. The old behavior, which exists only on x86 and CL versions up to
somewhere
+ * between 19.40.33811 and 19.41.33923:
+ * - If a negative float is cast to an unsigned integer, the result is
ULONG_MAX
+ * for uint32 and ULLONG_MAX for uint64.
+ * - If a float is cast to an unsigned long and the value is larger than
ULONG_MAX,
+ * the result is ULONG_MAX.
+ * 2. The new behavior (all x64 and x86 versions after the ones mentioned
above):
+ * - If a negative float is cast to an unsigned integer, the result is the
same as
+ first casting to the signed type, then casting to the unsigned type.
+ * - If a float is cast to an unsigned integer and the value is too large
for the type,
+ * the result is 0 for uint32 and 0x8000000000000000 for uint64.
+ * In the old version, the float to unsigned conversion was inlined and used
_ftoul2 and
+ * a comparison against 0x43e0000000000000 (9223372036854775808.0) to check
for overflow.
+ * In the new version, the float to unsigned conversion is done by a call to
_ftoul2_legacy,
+ * which checks for overflow by comparing against 0x5f800000
(18446744073709551616.0) and
+ * then forwards the call to either _ftol2 or _ftoul2.
