Previously methods `FPOptions::get*` returned unsigned value even if the
corresponding property was represented by specific enumeration type. With
this change such methods return actual type of the property. It also
allows printing value of a property as text rather than integer code.

This is recommit of 6c8041aa0f, reverted in de044f7562 because of some
fails. Original commit message is below.
This change allow a CastExpr to have optional FPOptionsOverride object,
stored in trailing storage. Of all cast nodes only ImplicitCastExpr,
CStyleCastExpr, CXXFunctionalCastExpr and CXXStaticCastExpr are allowed
to have FPOptions.

This change implements pragma STDC FENV_ROUND, which is introduced by
the extension to standard (TS 18661-1). The pragma is implemented only
in frontend, it sets apprpriate state of FPOptions stored in Sema. Use
of these bits in constant evaluation adn/or code generator is not in the
scope of this change.
Parser issues warning on unsuppored pragma when it encounteres pragma
STDC FENV_ROUND, however it makes syntax checks and updates Sema state
as if the pragma were supported.
Primary purpose of the partial implementation is to facilitate
development of non-default floating poin environment. Previously a
developer cannot set non-default rounding mode in sources, this mades
preparing tests for say constant evaluation substantially complicated.

This change allow a CallExpr to have optional FPOptionsOverride object,
stored in trailing storage. The implementaion is made similar to the way
used in BinaryOperator.
