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

29b488245d add setFloatMode builtin and std.math.floor
* 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)

29beb603b7 allow division and remainder operators sometimes
when the values are comptime known and the result would be the same,
allow `/` and `%` for signed integers and floats.

698829b772 change while syntax
Old:

```

```

New:

```
while (condition) : (expression) {}

This is in preparation to allow nullable and
error union types as the condition. See #357

c6605cba83 blocks check that their statements are void
closes #291

This changes the error message "return value ignored" to "expression value is ignored".
This is because this error also applies to {1;}, which has no function calls.

Also fix ignored expression values in std and test.
This caught a bug in debug.readAllocBytes where an early Eof error would have been missed.
See #219.

ad9040443c new compile errors for setGlobalAlign and setGlobalSection builtins
if you try to use them on an external variable or function
then you get a compile error, since the alignment/section
is set externally in this case.
