X87: [builtins] Unify most of the remaining Math builtins.

  port 0a0fe8fb8b06d5e90b082838739ebf44cab04028 (r37476)

  original commit message:
  Import fdlibm versions of acos, acosh, asin and asinh, which are more
  precise and produce the same result across platforms (we were using
  libm versions for asin and acos so far, where both speed and precision
  depended on the operating system so far). Introduce appropriate TurboFan
  operators for these functions and use them both for inlining and for the
  generic builtin.

  Also migrate the Math.imul and Math.fround builtins to TurboFan builtins
  to ensure that their behavior is always exactly the same as the inlined
  TurboFan version (i.e. C++ truncation semantics for double to float
  don't necessarily meet the JavaScript semantics).

  For completeness, also migrate Math.sign, which can even get some nice
  love in TurboFan.

  Drive-by-fix: Some alpha-sorting on the Math related functions, and
  cleanup the list of Math intrinsics that we have to export via the
  native context currently.
