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

d8227c79a2 limit generated C preprocessor tokens to alphabet 
closes #407

The mangling strategy replaces bytes outside the alphabet
with "_xx_" where xx is the hex code of the byte.

e81bf1c38c Return undefined in frexp instead of 0 on nan input

 - 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.
