reapply 112894:
...
Remove #uses comments from functions: they we're padded out to column 50
and were potentially confusing for externally visible functions.
going further, remove the "<i8**> [#uses=3]" comments entirely. They
add a lot of noise, confuse people about what the IR is, and don't add
any particular value. When the types are long it makes it really really
hard to read IR.
If someone is interested in this sort of thing, the right way to do this
is to implement an AsmAnnotationWriter that produces the same output, and
add a flag to llvm-dis (only) to produce this output.

For ARM stack frames that utilize variable sized objects and have either
...
large local stack areas or require dynamic stack realignment, allocate a
base register via which to access the local frame. This allows efficient
access to frame indices not accessible via the FP (either due to being out
of range or due to dynamic realignment) or the SP (due to variable sized
object allocation). In particular, this greatly improves efficiency of access
to spill slots in Thumb functions which contain VLAs.

- Change __builtin_ia32_palignr intrinsic type to match the pattern in clang.
...
- Add patterns to match the following MMX builtins:
* __builtin_ia32_vec_init_v8qi
* __builtin_ia32_vec_init_v4hi
* __builtin_ia32_vec_init_v2si
* __builtin_ia32_vec_ext_v2si
These builtins do not correspond to a single MMX instruction. They will have
to be lowered -- most likely in the back-end.
