when the integer part does not fit in the destination integer type * Also fix incorrect safety triggered for integer casting an `i32` to a `u7`. closes #1138 * adds compiler-rt function: `__floatuntidf` |

This compiler-rt library is ported from LLVM.
It's needed because LLVM emits library calls to compiler-rt when hardware lacks functionality, for example, 64-bit integer multiplication on 32-bit x86.
This library is automatically built as-needed for the compilation target and then statically linked and therefore is a transparent dependency for the programmer.
Any bugs should be solved by trying to duplicate the bug upstream.
- If the bug exists upstream, get it fixed with the LLVM team and then port the fix downstream to Zig.
- If the bug only exists in Zig, something went wrong porting the code, and you can run the C code and Zig code side by side in a debugger to figure out what's happening differently.
