"_cmd", "this", and "self".  These variables are handled
differently from all other external variables used by
the expression.  Other variables are used indirectly
through the $__lldb_arg operand; only _cmd, this, and
self are passed directly through the ABI.

There are two modifications:

 - I added a function to ClangExpressionDeclMap that
   retrives the value of one of these variables by name;
   and

 - I made IRInterpreter fetch these values when needed,
   and ensured that the proper level of indirection is
   used.

properly marked as valid.

Also modified the "memory read" command to be able to intelligently repeat
subsequent memory requests, so now you can do:

(lldb) memory read --format hex --count 32 0x1000

Then hit enter to keep viewing the memory that follows the last valid request.

linked against a debug LLVM, runs a variety of

ClangASTContext now calls this verifier whenever
it adds a Decl to a DeclContext, and the verifier
checks that the AccessSpecifier is sane.

- short strings that don't start with a capitol letter unless the name is a

- no trailing newline character
- should be one line if possible

Implemented a first pass at adding "--gdb-format" support to anything that
accepts format with optional size/count.

An example (with /Developer/usr/bin/lldb vs. /usr/bin/gdb):

parser.  Now expression like the following work as
expected:

-
(lldb) expr struct { int a; int b; } $blah = { 10, 20 }
<no result>
(lldb) expr $blah
(<anonymous struct at Parse:6:5>) $blah = {
  (int) a = 10
  (int) b = 20
}
-

Now the IRForTarget subsystem knows how to handle
static initializers of various composite types.

Also removed an unnecessary parameter from
ClangExpressionDeclMap::GetFunctionInfo.

we handle the mangled name directly, which is more

OptionGroupFormat. Updated OptionGroupFormat to be able to also use the
"--size" and "--count" options. Commands that use a OptionGroupFormat instance
can choose which of the options they want by initializing OptionGroupFormat
accordingly. Clients can either get only the "--format", "--format" + "--size",
or "--format" + "--size" + "--count". This is in preparation for upcoming
chnages where there are alternate ways (GDB format specification) to set a
format.

command if, for example, we have issued 'display a' and 'display b' which turn into
"target stop-hook add -o 'expr -- a'" and "target stop-hook add -o 'expr -- b'".

Plus some minor change in TestAbbreviations.py to conditionalize the platform-specific
