[CLANG][PATCH][FPEnv] Add support for option -ffp-eval-method and extend #pragma float_control similarly 

The Intel compiler ICC supports the option "-fp-model=(source|double|extended)"
which causes the compiler to use a wider type for intermediate floating point
calculations. Also supported is a way to embed this effect in the source
program with #pragma float_control(source|double|extended).
This patch extends pragma float_control syntax, and also adds support
for a new floating point option "-ffp-eval-method=(source|double|extended)".
source: intermediate results use source precision
double: intermediate results use double precision
extended: intermediate results use extended precision

* ``maytrap`` The compiler avoids transformations that may raise exceptions that would not have been raised by the original code. Constant folding performed by the compiler is exempt from this option.
* ``strict`` The compiler ensures that all transformations strictly preserve the floating point exception semantics of the original code.
.. option:: -ffp-eval-method=<value>
Specify the floating-point evaluation method.
Valid values are: ``source``, ``double``, and ``extended``.
The default value is target-specific, typically ``source``. Details:
* ``source`` The compiler uses the floating-point type declared in the source program as the evaluation method.
* ``double`` The compiler uses ``double`` as the floating-point evaluation method for all float expressions of type that is narrower than ``double``.
* ``extended`` The compiler uses ``long double`` as the floating-point evaluation method for all float expressions of type that is narrower than ``long double``.
