0eff39f2e2 Enable support for returning i1, i8, and i16. Nothing special todo as it's the 
callee's responsibility to sign or zero-extend the return value.  The additional
test case just checks to make sure the calls are selected (i.e., -fast-isel-abort
doesn't assert).

55e9587469 Fix eabi calling convention when a 64 bit value shadows r3. 
Without this what was happening was:

* R3 is not marked as "used"
* ARM backend thinks it has to save it to the stack because of vaarg
* Offset computation correctly ignores it
* Offsets are wrong

5bafff36c7 Add support for ARM's Advanced SIMD (NEON) instruction set. 
This is still a work in progress but most of the NEON instruction set
is supported.

385f5a99ec Address review comments: add 3 ARM calling conventions. 
Dispatch C calling conv. to one of these conventions based on
target triple and subtarget features.

0eebf653a7 The attached patches implement most of the ARM AAPCS-VFP hard float 
ABI. The missing piece is support for putting "homogeneous aggregates"
into registers.

1c2c462d0f Remove unnecessary references to f32 types. After specifying that f32 
should be bit-converted to i32, it is sufficient to list only i32 in
subsequent definitions.
