0f21d3d4d1 LLVM: always add argument attributes to calls 
These are needed for correctness. There's no reason to only add them for
function pointers.

f26dda2117 all: migrate code to new cast builtin syntax 
Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:

* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change

bigger alignment than the raw type.

a06185f362 C ABI: Add tests for complex float/double support 
These tests will be failing on many platforms until #8465 is resolved.

Luckily, the particular function signature used for __divXc3 and __mulXc3
seems to be OK on x86-64.
