The code path is tested by behavior tests.

Thanks to various contributors, but mostly Marc Tiehuis,
bigint.cpp now has full coverage.

f6cd68386d @bitreverse intrinsic, part of #767 (#1865)
* bitreverse - give bswap behavior

* bitreverse, comptime_ints, negative values still not working?

* bitreverse working for negative comptime ints

* Finished bitreverse test cases

* Undo exporting a bigint function. @bitreverse test name includes ampersand

* added docs entry for @bitreverse

09bd4a9a86 compile-time f32, f64 operations are now correctly lossy
previously we used the bigfloat abstraction to do all
compile-time float math. but runtime code and comptime code
are supposed to get the same result. so now if you add a
f32 to a f32 at compile time it does it with f32 math
instead of the bigfloat. float literals still get the
bigfloat math.

35d3444e27 more intuitive left shift and right shift operators
Before:
 * << is left shift, not allowed to shift 1 bits out
 * <<% is left shift, allowed to shift 1 bits out
 * >> is right shift, allowed to shift 1 bits out

After:
 * << is left shift, allowed to shift 1 bits out
 * >> is right shift, allowed to shift 1 bits out
 * @shlExact is left shift, not allowed to shift 1 bits out
 * @shrExact is right shift, not allowed to shift 1 bits out

Closes #413
