Bug 1484720 - Part 2: Remove always-false isSlowPlatform() test function. r=jya

isSlowPlatform() is always false because we no longer support Android 2.3 or B2G.

Also remove unused functions isWindows32() and isAndroid(). They were added in bug 1485875, but the callers were later removed in Windows bug 1475564 and Android bug 1368843.

Depends on D33423
