75995b5e86 Data formatter support for libc++ std::atomic<T>
On libc++ std::atomic is a fairly simple data type (layout wise, at least), wrapping actual contents in a member variable named "__a_"

All the formatters are doing is "peel away" this intermediate layer and exposing user data as direct children or values of the std::atomic root variable

Fixes rdar://24329405

9293fc4185 Better scheme to lookup alternate mangled name when looking up function address.
Summary:
This change is relevant for inferiors compiled with GCC. GCC does not
emit complete debug info for std::basic_string<...>, and consequently, Clang
(the LLDB compiler) does not generate correct mangled names for certain
functions.

This change removes the hard-coded alternate names in
ItaniumABILanguageRuntime.cpp.

Before the hard-coded names were put in ItaniumABILanguageRuntime.cpp, one could
not evaluate std::string methods (ex. std::string::length). After putting in
the hard-coded names, one could evaluate them. However, it did not still
enable one to call methods on, say for example, std::vector<string>.
This change makes that possible.

There is some amount of incompleteness in this change. Consider the
following example:

std::string hello("hello"), world("world");
std::map<std::string, std::string> m;
m[hello] = world;

One can still not evaluate the expression "m[hello]" in LLDB. Will
address this issue in another pass.

9fa1147052 Some minor improvements on the symtab parsing code
* Remove an unneccessary re-computaion on arch spec from the ELF file
* Use a local cache to optimize name based section lookups in symtab
  parsing
* Optimize C++ method basename validation with replacing a regex with
  hand written code

These modifications reduce the time required to parse the symtab from
large applications by ~25% (tested with LLDB as inferior)

045c829223 Fix evaluation of unicode character arrays (char16_t[] and char32_t[])
Suppose we have the UTF-16 string:
    char16_t[] s = u"hello";
Before this patch, evaluating the string in lldb would get:
    (char16_t [6]) $0 = ([0] = U+0068 u'h', [1] = U+0065 u'e', [2] = U+006c u'l', [3] = U+006c u'l', [4] = U+006f u'o', [5] = U+0000 u'\0')
After applying the patch, we now get:
    (char16_t [6]) $0 = u"hello"

5f9d310640 Add a new type of plugin: Language plugin
The Language plugin is menat to answer language-specific questions that are not bound to the existence of a process. Those are still the domain of the LanguageRuntime plugin

The Language plugin will, instead, answer questions such as providing language-specific data formatters or expression evaluation

At the moment, the interface is hollowed out, and empty do-nothing plugins have been setup for ObjC, C++ and ObjC++
