The previous solution was problematic because the change was language-
visble via the isUnsigned trait. Now, pointers are simply explicitly
checked for in the relevant places. (Note that there might be cases in
the diff where a direct isunsigned() call would have been appropriate –
I only checked for instances where the type clearly cannot be a pointer,
but chose to go the safe route in replicating existing behavior
otherwise).
Fixes DMD testcase 'traits'.
Fixed a bunch of the built-in typeinfos for arrays, they did not inherit TypeInfo_Array.
Applied patch to tango/text/convert/Layout.d by fvbommel, closes#47 .
Cleaned up some type code.
Replaced uses of llvm::Type with LLType (a typedef), same for Value and Constant.
Fixed a few cases where typeinfo for user structs could be emitted multiple times, seems to still be some cases of this :/
Lots of bugfixes.
Added support for special foreach on strings.
Added std.array, std.utf, std.ctype and std.uni to phobos.
Changed all the .c files in the gen dir to .cpp (it *is* C++ after all)
