Add math functions for f16 and f128
...
This adds missing functions for math operations on the new float types.
Platform support is pretty spotty at this point, since even platforms
with generally good support can be missing math functions.
`std/build.rs` is updated to reflect this.

Document the column numbers for the dbg! macro
...
The line numbers were also made consistent, some examples used the line numbers as shown on the playground while others used the line numbers that you would expect when just seeing the documentation.
The second option was chosen to make everything consistent.

Add tests for f16 and f128
...
This suite tests all library functions that are now available for the
types. Tests are only run on certain platforms where `f16` and `f128`
are known to work (have symbols available and don't crash LLVM).

stdio: Document no support for writing to non-blocking stdio/stderr
...
Printing to stdio/stderr that have been opened with non-blocking
(O_NONBLOCK in linux) can result in an error, which is not handled
by std::io module causing a panic.

Add comments about stdout locking
This is the source of some confusion regarding the `println!` macro:
* https://llogiq.github.io/2017/06/01/perf-pitfalls.html#unbuffered-io
* https://news.ycombinator.com/item?id=18794930
* https://reddit.com/r/rust/comments/5puyx2/why_is_println_so_slow/dcua5g5/
* https://reddit.com/r/rust/comments/ab7hsi/comparing_pythagorean_triples_in_c_d_and_rust/ecy7ql8/
In some of these cases it's not the locking behavior where the bottleneck lies, but it's still mentioned as a surprise when, eg, benchmarking a million `println!`'s in a very tight loop.
If there's any stylistic problems please feel free to correct me! This is my first contribution and I want to get it right 🦀

UPD: the fallback to considering *all* `macro_rules` in the crate for unresolved names is not removed in this PR, it will be removed separately and will be run through crater.
