Description

What is the purpose of this pull request?

This pull request:

• fixes math/base/assert/is-odd and is-oddf returning true for every finite value whose magnitude exceeds the maximum safe integer (2^53-1 and 2^24-1, respectively). x-1 rounds back to an even value, so, e.g., isOdd( 1.0e300 ) returned true.
• fixes the sign of pow( -2.0, 2^60 ), which returned -Infinity instead of Infinity.
• keeps the documented behavior for ±Infinity.
• returns 1 for -1 raised to an even integer in math/base/special/pow. Before, pow( -1.0, 1.0e300 ) returned -1 because of the is-odd bug, and with only the is-odd fix it would return Infinity. This matches powf.
