LDC predefined identifiers

I can see names like:

LDC
LLVM
LLVM64
Win64
Win32
Windows
D_Version2

=>

They may become more orthogonal, and there's no need to keep both LDC and LLVM:

Bit_64
Bit_32
Windows
Linux
Compiler_LDC
Compiler_DMD
Compiler_GDC
Stdlib_Phobos
Stdlib_Tango
D_Version_1
D_Version_2
And some more.
