Fix x86 type conversions. test-art-host-oat passes.

- test-art-host-oat enabled in test builds.

- Created inline versions of float-to-int and double-to-int.

- Fixed calls to helper functions for long-to-float/double and
  float/double-to-long.

- Removed storePair and replaced its use with storeBaseDispWide (fixes
  iput-wide and aput-wide with doubles).

- Renamed helper functions to have art_ prefix.

- Fixed move-exception to store the result back.

- Fixed floating point comparison when the destination reg is the same as
  a source. The typing would get confused since the source is floating
  point, but the result is int, and a clobber is needed to overwrite the
  expected result type. A similar thing happens in float/double-to-int.
