[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.
