Change Math method from @FastNative to @CriticalNative.
MathBenchmarks.java#timePow results on taimen's little cores
fixed at frequency 1401600 with forced JIT compilation:
- before:
- X32: 356.33
- X64: 357.31
- after:
- X32: 315.39
- X64: 315.37
Similar improvements are seen for timeIEEEremainder and
timeLog1p.
Test: Rely on TreeHugger.

jni: Switch to @FastNative for all JNI functions.
Switches all (248) methods that previously used !bang JNI in art/libcore
to all use @FastNative.
As a nice benefit, this should be about 1.5x faster than before for those method calls.
This measures out to a 3% startup time improvement for system_server.

Refined comment in FP abs() implementation.
Rationale:
As a "quality of implementation", rather than pure "spec compliance",
we require that Math.abs() clears the sign bit (but changes nothing else)
for all numbers, including NaN (signaling NaN may become quiet though).

Changed semantics of FP Math.abs() to impact bit sign (but nothing else).
Rationale:
As a "quality of implementation" rather than pure "spec compliance"
we require that Math.abs() clears the sign bit (but changes nothing

This CL has a corresponding Art test.

Update java.io.File to 8u60
- File fields path/prefixLength are final (and #readObject
is implemented using Unsafe).
- Temp file name generation uses longs. Restored TempDirectory
(removed in 3a4b7ebcde0ba6b7dce5c6118fa6a3da77b3d21d) inner
class, to minimize the diff from upstream.
- Javadoc and formating updates
Test: vogar run on all io tests I could find.

Fix Math.round bug for large integral arguments
Cherrypick JDK 8 changeset 8052:917fffe971c8. This uses integer
manipulations to compute the result for all arguments for which
we can't just cast the argument.
Added required imports to make the JDK 8 patch compile.

StrictMath implementations gives us great
