Win64 ABI: Rewrite magic __c_long_double struct as double
...
__c_long and __c_ulong have already been passed directly as LL structs
containing a single 32-bit value, i.e., as 32-bit scalars in the end.
__c_long_double on the other hand was rewritten to a 64-bit integer as any
other 64-bit POD struct, and so passed in a GP register instead of an XMM
register.

Respect explicit type alignments for LL args passed im- and explicitly by value
...
And for sret args too, except for MSVC targets.
At least on Win64, the sret align attributes lead to ICEs for std.bitmanip
and std.uni (release only), when computing the known alignment in the LLVM
inliner pass:
Assertion failed: I->getParent()->getParent() ==
Q.CxtI->getParent()->getParent() && "Got assumption for the wrong function!",

Use C calling convention for variadic functions on x86.
...
0.15.1 used stdcall convention everywhere. But the ABI change in 0.15.2
requires use of the C calling convention for variadic calls on x86
because the stdcall convention does not support vararg functions.
Solution is to check the llvm::FunctionType if the function has varargs.
This commit also makes the C calling convention the global default
because according to the LLVM documentation the fastcc convention used
for D linkage does not support varargs.
This fixes issue #1000 .

Just like DMD. Inline assembly in druntime/phobos depends on this.
Only relevant for MinGW-w64 as MSVC uses 64-bit real.

Refactor Win64 ABI.
...
I've decided to use a consistent scheme here - types are returned the same
way as they are passed as arguments. So cfloat as 64-bit struct in RAX,
cdouble/creal and 80-bit real/ireal as types > 64 bit via sret.
MS allows using the x87 stack, but there are no official guidelines as
they don't use x87 at all.
