The test mjsunit/regress/regress-sqrt compares the result of Math.sqrt function
       when using full-compiler and turbofan/crankshaft compiler seperately. But according
       to glibc bug fixing(https://sourceware.org/bugzilla/show_bug.cgi?id=14032). The
       glibc implementation of std::sqrt() (It is invoked in the generated code when
       full-compiler is used.) will change since glibc 2.19.

       In order to keep consistence of Math.sqrt translation in turbofan compiler
       and the pass of mjsunit/regress/regress-sqrt. we translate the Math.sqrt func
       according to the same fix in glibc change.  If the GLIBC version >=2.19, we will
       set the precision to Double. (the original is extended-double).

       This fix is to fix the same issue in https://codereview.chromium.org/606403002 for
       crankshaft. This fix may be ported for crankshaft too.
