Got the segfault in the sieve program to go away by changing the 
default calling convention for all linkage types in gen/abi.cpp 
to C, just as Kai did on PPC64.  I don't get any "Aborted" tests 
now either.

One issue cropping up in std.format appears to be with structs 
that use alias this for a member, specifically these two:

The first one returns false, the second one returns a junk number 
for the imaginary component of the complex number.  Not sure why 
it fails for some structs that use alias this and not others, 
going to look into it.

Another issue is that the dwarf output for debugging might be 
corrupted somehow.  If I compile sieve.d and have it run fine 
against non-debug druntime/phobos, it then segfaults in different 
places if I link it against debug druntime or phobos, which are 
simply compiled with the -g flag.

Finally, many modules still claim that they assert in a test in 
std.format, when std.format itself says that test passes, weird.
