fc6c340661 Optimize ABIRewrite system for lvalues 
Allow ABIRewrites to return the D parameter's LL value directly.
Most rewrites store to memory anyway, so let the D parameter point
directly to that memory instead of a dedicated alloca bitcopy.

98a608e925 First proof -of-concept for objc support 
This at least shows a path forward.  Pretty much a kludge to at this
point, but passes the tests.

44b0f7b615 driver/gen/ir: clang-format the world 
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.

80c677be46 Slightly refactor ABIRewrite interface for clarification 
* put(): pass DValue alone, without explicit D type
* get(): pass LLValue instead of a faked DValue

ee50259dfd C ABI: Do not pass empty structs as parameters at all 
This is most visible on x86 (32-bit), where the stack
alignment is off otherwise.

This change is quite messy because many places assumed
that there was always exactly one LLVM parameter per
TypeFunction::parameters entry.

6bb2c30c05 SysV ABI: prevent structs from being only partially passed in registers. 
Only for formal parameters for now, optional args still need to be fixed.

fe39da53e3 Merge of 2.065.0-b3.

5aa06092cd Fix issue #570. 
The use of std::vector<> is replaced by Array<> for MSVC only. This fixes
the error. But it is still unclear why std::vector<> fails.

b021a2930d Remove MSVC crap. 
The code was a work around and did not solve the underlying problem.

cb341586e3 First merge of 2.064 beta. 
This corresponds to DMD commit a913ce4bc59a94a022a27e390fc841f4aededffb.

1242be25d0 Remove unused, empty Ir type. 
The codegen parameter was changed to IRState instead of
removing it to set the stage for an eventual eradication
of the gIR global.

c7c1c25f15 DValue: struct->class. 
This is in line with an incoming upstream change making all
polymorphic structs classes, and also matches common coding
conventions.

beed5c3044 Get rid of empty IrBase class. 
It isn't useful in any way now that the GC is out of the
picture, and the existance of a "dummy" toChars() method is
annoying when debugging.

f806ec0ed5 Attribute holds no longer multiple values in LLVM 3.3. 
The solution is to replace Attribute with AttrBuilder in IrFuncTyArg.
Then the argument attributes can be easily manipulated and transformed
into the final AttributeSet.

5f37ae30cf LLVM 3.3: class Attributes is renamed to Attribute. 
Some other renamings took place in "llvm/Attributes.h" but only this causes
compile errors in LDC.
Also uses new location of "llvm/IRBuilder.h".
