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

3e8af78895 Merge branch 'math' 
This merges the standard library math functions that
Marc Tiehuis (@tiehuis) has been working on. Marc has
joined the Zig organization and now has commit access.
Thank you for this huge contribution to Zig.

Closes #374.

e81bf1c38c Return undefined in frexp instead of 0 on nan input 
This is more in line what usual C implementations do.

5bbec42a4e Add math special case tests and general fixes 
- Should cover special case inputs for most functions
 - Fixed a number of runtime panicking behaviour reliant on shift
   overflow/division by zero etc.

4efb9ae2e5 Get tests passing under release mode 
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.

4c16f9a3c3 Add math library 
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.

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)
