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.

Don't use the fact that we stopped with a "Breakpoint" stop reason to decide to step over the breakpoint.  It's 
better to check directly whether there is a breakpoint site at the PC.

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.

This could be 'null' or the empty string, DIDescriptor::getStringField
coalesces the two cases anyway so it's just a matter of legible/efficient
representation.

The change in behavior of the DICompileUnit::get* functions could be
subsumed by the full verification check - but ideally that should just be an
assertion if we could front-load the actual debug info metadata failure paths.

In my previous commits I failed to realise that my new requires lines fully
disabled these tests. We now properly check if we are in an asserts build and
only disable the tests if assertions are not available.

Increase the cost of v8/v16-i8 to v8/v16-i32 casts and truncates as the backend
currently lowers those using stack accesses.

This was responsible for a significant degradation on
MultiSource/Benchmarks/Trimaran/enc-pc1/enc-pc1
where we vectorize one loop to a vector factor of 16. After this patch we select
a vector factor of 4 which will generate reasonable code.

  for (compte = 0; compte <= 31; compte++) {

-ccc-install-dir is supposed to cause the compiler to behave as-if it
were installed in the indicated location. It almost does, but misses
anything that's relying on the resource directory (libc++ header search,
in particular). The resource dir is resolved too early, before command
line args are handled.

The fix is simply to move handling of the resource dir until after we
know if a -ccc-install-dir is present.
