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.

As much as I hate to leave this hacky code in that adds some d and q registers to ARM registers, I must leave it in.
The code is now fixed to not just assume ANY arm target will have registers in a certain order. We now verify the common regs are the same name and byte size before adding the d and q regs.

This is a very basic implementation of a library that easily allows to drive LLDB.framework to write test cases for performance
This is separate from the LLDB testsuite in test/ in that:
a) this uses C++ instead of Python to avoid measures being affected by SWIG
b) this is in very early development and needs lots of tweaking before it can be considered functionally complete
c) this is not meant to test correctness but to help catch performance regressions
There is a sample application built against the library (in darwin/sketch) that uses the famous sample app Sketch as an inferior to measure certain basic parameters of LLDB's behavior.
The resulting output is a PLIST much like the following:
<?xml version="1.0" encoding="UTF-8"?>

Areas for improvement:
- code cleanups (I will be out of the office for a couple days this coming week, but please keep ideas coming!)
- more metrics and test cases
- better error checking
This toolkit also comprises a simple event-loop-driven controller for LLDB, similar yet much simpler to what the Driver does to implement the lldb command-line tool.

counters for a variety of metrics associated
with expression parsing. This should give some
idea of how much work the expression parser is
doing on Clang's behalf, and help with hopefully
reducing that load over time.

Make dynamic type detection faster by using the AST metadata to help out and allow us not to complete types when we don't need to.
After running "purge" on a MacOSX system, the Xcode variables view now populates more than 3x faster with this fix.

- change string "ERROR" to "FAIL" to match clang lit test results
Also, make LLDB tests work on machines that do not have svn and/or git installed

"compile_units" returns an array of all compile units in a module as a list() of lldb.SBCompileUnit objects.
"compile_unit" returns a compile unit accessor object that allows indexed access, search by full or partial path, or by regex:
(lldb) script
comp_unit = lldb.target.module['TextEdit'].compile_unit['Document.m']
comp_unit = lldb.target.module['TextEdit'].compile_unit['/path/to/Document.m']
comp_unit = lldb.target.module['TextEdit'].compile_unit[0]
comp_unit = lldb.target.module['TextEdit'].compile_unit[1]
for comp_unit in lldb.target.module['TextEdit'].compile_unit[re.compile("\.m$")]
print comp_unit
This helps do quick searches and scripting while debugging.

I used this to verify that the debug map line tables were the same as previous LLDB releases prior to my change in the DWARF in .o file linking.

- missing definitions were causing different definitions of type 'off_t', resulting in linker errors
- fix is to define _LARGEFILE_SOURCE and _FILE_OFFSET_BITS=64
