The part needing most attention was ddmd.root.ctfloat, ddmd.target (incl. gen/target.cpp) and ddmd.builtin. The front-end is now prepared for elaborate compile-time floating-point types to allow for proper cross- compilation. This version still uses the host's `real` type for compile-time reals, except for MSVC hosts, which still use 64-bit doubles (when compiled with DMD host compiler too). Some other changes: * semantic*() of Statements extracted from statement.d to statementsem.d * mangle() -> mangleToBuffer() * Identifier::string -> toChars() * Token::float80value => floatvalue * Dsymbol::isAggregateMember() => isMember() * BoolExp is no more * ddmd.root.ctfloat: LDC-specific CTFE builtins
