1fb788ac89 aarch64: fix index base register for AArch64 
The base is passed in `x3`, not in `x2`.  This fixes the indexing base
so that the right value is used.

4da814b18a aarch64: Fix handling of aggregates larger than 16 bytes 
Instead of allocating stack space for a pointer we would allocate stack
space for the actual aggregate size.

d76975dbd2 Define FFI_SIZEOF_JAVA_RAW for aarch64 ILP32 
Like x32, aarch64 ILP32 needs to define FFI_SIZEOF_JAVA_RAW.  This fixes
the java interpreter.

536366349c aarch64: implement the trampoline table workaround for ffi closures on Apple systems 
This is a direct copy/paste port of the ARM code, with changes because of Aarch64 pc-relative addressing restrictions.

05e65b4e20 aarch64: rewrite range syntax into list to appease Clang 
Clang's assembler in Xcode 6 appears to choke when the operand of st4 is a range, but is happy with a list.

0e41c73b09 aarch64: Move x8 out of call_context 
Reduces stack size.  It was only used by the closure, and there
are available argument registers.

4a3cbcaa4f aarch64: Unify scalar fp and hfa handling 
Since an HFA of a single element is exactly the same as scalar,
this tidies things up a bit.

12cf89ee04 aarch64: Move return value handling into ffi_closure_SYSV

4fe1aea121 aarch64: Move return value handling into ffi_call_SYSV 
This lets us pass return data directly to the caller of ffi_call
in most cases, rather than storing it into temporary storage first.

8c8161cb62 aarch64: Tidy up abi manipulation 
Avoid false abstraction, like get_x_addr.  Avoid recomputing data
about the type being manipulated.  Use NEON insns for HFA manipulation.

Note that some of the inline assembly will go away in a subsequent patch.

77c4cddca6 aarch64: Simplify AARCH64_STACK_ALIGN 
The iOS abi doesn't require padding between arguments, but
that's not what AARCH64_STACK_ALIGN meant.  The hardware will
in fact trap if the SP register is not 16 byte aligned.

b5f147d847 aarch64: Always distinguish LONGDOUBLE 
Avoid if-deffery by forcing FFI_TYPE_LONGDOUBLE different
from FFI_TYPE_DOUBLE.  This will simply be unused on hosts
that define them identically.

38b54b9c18 aarch64: Improve is_hfa 
The set of functions get_homogeneous_type, element_count, and is_hfa
are all intertwined and recompute data.  Return a compound quantity
from is_hfa that contains all the data and avoids the recomputation.

0f4e09d27d Fix non-variadic CIF initialization for Apple/ARM64 
Turns out `aarch64_nfixedargs` wasn't initialized in the non-variadic
case, resulting in undefined behavior when allocating arguments.
