This does not fix the underlying issue in pow at this stage, but we may
be able to narrow down the cause after adding tests for specific edge
cases in functions.
This covers the majority of the functions as covered by the C99
specification for a math library.
Code is adapted primarily from musl libc, with the pow and standard
trigonometric functions adapted from the Go stdlib.
Changes:
- Remove assert expose in index and import as needed.
- Add float log function and merge with existing base 2 integer
implementation.
See https://github.com/tiehuis/zig-fmath.
See #374.
* skip installing std/rand_test.zig as it's not needed beyond running
the std lib tests
* add std.math.floor function
* add setFloatMode builtin function to choose between
builtin.FloatMode.Optimized (default) and builtin.FloatMode.Strict
(Optimized is equivalent to -ffast-math in gcc)
* add `@divTrunc` and `@divFloor` functions
* add `@rem` and `@mod` functions
* add compile error for `/` and `%` with signed integers
* add `.bit_count` for float primitive types

Old:
```
while (condition; expression) {}
```
New:
```
while (condition) : (expression) {}
```
This is in preparation to allow nullable and
error union types as the condition. See #357

sadly the quality of the intel dialect in llvm's assembly
parser has many frustrating bugs, and generally has unfortunate
syntax.
the plan is to use AT&T for now since it at least works,
and eventually zig will have its own assembly parser for
x86 and it will be as close to NASM as possible.
* add ability to add assembly files when building an exe, obj, or lib
* add implicit cast from `[N]T` to `?[]const T` (closes#343)
* remove link_exe and link_lib in favor of allowing build_exe and
build_lib support no root zig source file
