3a0bfeb9d2 Fix coverage build command 
Seems like this was deleted at some stage.

coverage command works as expected once removed. Do correct me if I've missed something, though.

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

d8227c79a2 limit generated C preprocessor tokens to alphabet

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

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.
