608ce9852e Emit symbols by default as COMDATs 
That's apparently what DMD does and what currently happens for all
non-MSVC targets anyway.

For MSVC, we need this to enforce the `any` selection instead of
`no duplicates`, otherwise the linker complains about multiply defined
symbols and refuses to link without an extra command line option
(which in turn outputs a non-suppressable warning).

51074b0ce5 Zero extend char and wchar 
Add LLVM zeroext attribute to char and wchar types so they are
compatible with similar sized C ABI unsigned int types.

In particular, this is needed for ARM (fixes runnable/cppa.d at -O3)
and seems like proper behavior for all supported ABIs even though the
x86 ABIs get by without this.

5a84c2524d DtoType: Handle enum forward references 
Note that we don't set t->ctype (we'd need a new IrTypeEnum or something
along the lines). This is okay because we don't do so for enums in either
case, even in the normal code paths. Enums are regarded as being
"transparent" in that sense. We might want to rethink this in the future,
though.

Fixes DMD test case 'ice13792'.

29ce4012af dmd2 --> ddmd. Merge (almost all of) our changes to dmd source into the new D source of dmd 2.069.2. 
Also adds the CMake infrastructure to compile and link the D source files.

The build is partially broken:
- A few files in Phobos and druntime do not build
- MSVC build is broken because of unresolved symbols involving reals

This uses the LLVM style, which makes sense for sharing code
with other LLVM projects. The DMD code we use will soon all
be in D anyway.

b92e377d49 Fix definition of D_LP64. 
LP64 defines a C environment with 64bit pointers and char/short/int/long
are 8/16/32/64bit. char/short/int/long have defined sizes in D. We need
to look only at the pointer size.

There are now 64bit environments with 32bit pointers. Examples are
x32 in Intel and N32 on MIPS64. For these environments D_LP64 should
not defined but the global.param.is64bit is still true. The definition
of size_t is also affected. If only 32bit are addressable then size_t
should also be a 32bit type. (This is not required by C standard but
common practize.)

The net result is that not only the definition of D_LP64 must be changed
but also DtoSize_t().
