In r176898 I updated the cost model to reflect the fact that sext/zext/cast on
v8i32 <-> v8i8 and v16i32 <-> v16i8 are expensive.

This test case is so that we make sure to update the cost model once we fix
CodeGen.

The step by running from branch to branch pretty much works with this checkin (at least for x86_64) but is still
turned off, it needs more qualification.  If you want to play with it, change the initialization of m_use_fast_step
to true.

Drop the old f registers from debugserver's register list.  Add the
NEON 128-bit q registers to debugserver, support reading and writing.
Add the new contains / invalidates mappings for the s, d, and q 
registers so lldb will know what registers overlay what other registers.
Change the default format of s and d registers to be floating point
instead of hex.  Remove some UTF-8 hyphen chars in comments in the ARM
register number definition headers.
