Fix handling of backslashes in Args parsing
Summary:
Presently Args::SetCommandString allows quotes to be escaped with backslash. However, the
backslash itself is not removed from the argument, nor there is a way to escape the backslash
itself. This leads to surprising results:
"a b" c" -> 'a b', 'c' # Here we actually have an unterminated quote, but that is ignored
"a b\" c" -> 'a b\" c' # We try to escape the quote. That works but the backslash is not removed.
"a b\\" c" -> 'a b\\" c' # Escaping the backslash has no effect.
This change changes quote handling to be more shell-like:
- single quotes and backquotes are literal and there is no way to escape the closing quote or
anything else inside;
- inside double quotes you can use backslash to escape the closing quote and another backslash
- outside any quotes, you can use backslash to escape quotes, spaces and itself.
This makes the parsing more consistent with what the user is familiar and increases the
probability that pasting the command line from shell to the "process launch" command "just work".

the temporary MDNodes we were creating as DIScopes instead
of DITypes (in DIScope::getRef).
This proposal changes llgo to use DIBuilder's
createReplaceableCompositeType method to create a DIType
that can be RAUW'd.

bindings/go: expose DIBuilder::createReplaceableCompositeType
Summary:
We extend the DIBuilder type, adding a method for creating
replaceable composite types. This is necessary for creating
debug info describing self-referential types.

[clang-tidy] Assert related checkers
This patch contains two assert related checkers. These checkers are the part of
those that is being open sourced by Ericsson
(http://lists.cs.uiuc.edu/pipermail/cfe-dev/2014-December/040520.html).
The checkers:
AssertSideEffect:
/// \brief Finds \c assert() with side effect.
///
/// The conition of \c assert() is evaluated only in debug builds so a condition
/// with side effect can cause different behaviour in debug / relesase builds.
StaticAssert:
/// \brief Replaces \c assert() with \c static_assert() if the condition is
/// evaluatable at compile time.
///
/// The condition of \c static_assert() is evaluated at compile time which is
/// safer and more efficient.

2) Now supports -no-compiler-generated command line argument to
exclude compiler generated types.
3) Prints base class list.
