fd75e73ee9 add f16 type 
Add support for half-precision floating point operations.

Introduce `__extendhfsf2` and `__truncsfhf2` in std/special/compiler_rt.

Add `__gnu_h2f_ieee` and `__gnu_f2h_ieee` as aliases that are used in
Windows builds.

The logic in std/special/compiler_rt/extendXfYf2.zig has been reworked
and can now operate on 16 bits floating point types.

`extendXfYf2()` and `truncXfYf2()` are marked `inline` to work around
a not entirely understood stack alignment issue on Windows when calling
the f16 versions of the builtins.

closes #1122

c7804277bf @floatToInt now has safety-checked undefined behavior 
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`

dc8bda7e02 Add arbitrary-precision integer to std 
A few notes on the implementation:

 - Any unsigned power of two integer type less than 64 bits in size is supported
 as a Limb type.
 - The algorithms used are kept simple for the moment. More complicated
 algorithms are generally only more useful as integer sizes increase a
 lot and I don't expect our current usage to be used for this purpose
 just yet.
 - All branches (practically) have been covered by tests.

See 986a2b3243/bench
for rough performance comparison numbers.

Closes #364.

fc6446702e clean up std.ArrayList 
* add `std.debug.assertError`
 * `std.ArrayList` update everything to follow `self` convention
 * rename `std.ArrayList.set` to `std.ArrayList.setOrError`
 * add `std.ArrayList.set` which asserts

Before 1.0.0 we might remove some of this API, because you can use
`toSlice()` for everything, but it's ok to add these functions as
an experiment before then.
