Remove a bitrotted test.

Change-Id: I4c44f2da0544dbfde8e340f7f477191725c5fb8b
Avoid deadlock between ActivityManagerService and ProcessStatsService.

Root Cause:
Case 1
getStatsOverTime(#483) // lock mWriteLock, wait AMS
async performWriteState(#269) // lock mPendingWriteLock, wait mWriteLock
writeStateLocked(#218) // lock AMS, wait mPendingWriteLock

Case 2
getStatsOverTime(#483) // lock mWriteLock, wait AMS
writeStateSyncLocked,writeStateLocked(#269) // lock AMS, wait mWriteLock

Solution:
Reduce nested lock.

Replacing FloatMath native implementation with calls to Math

On modern versions of Android running in AOT mode
FloatMath is slower than Math. Calls to Math.sqrt(),
etc. are replaced by intrinsics which can be as small
as a single CPU opcode.

When running in interpreted mode the new
implementation is unfortunately slower, but I'm
judging this acceptable and likely to be improved
over time. This change saves a small amount of native
code.

Example timings:

Mako AOSP AOT:

Method: Original / New / Direct call to Math
ceil: 596ns / 146.ns / 111ns
sqrt: 694ns / 56ns / 25ns

Mako AOSP interpreted:

Method: Original / New / Direct call to Math
ceil: 1900ns / 2307ns / 1485ns
sqrt: 1998ns / 2603ns / 1788ns

Other calls Mako AOT:

Method: Original / New
cos: 635ns / 270ns
exp: 566ns / 324ns
floor: 604ns / 150ns
hypot: 631ns / 232ns
pow: 936ns / 643ns
sin: 641ns / 299ns

The advice to use Math directly, in preference to
FloatMath, is still good. FloatMath will be deprecated
separately.
