Teach clang driver about Cortex-A53 and Cortex-A57.

Adds some Cortex-A53 strings where they were missing before.
Cortex-A57 is entirely new to clang.

Doesn't touch code only used by Darwin, in consequence of which
one of the A53 lines has been removed.

Add driver support for FP, SIMD and crypto defaults.

Although we wire up a bit for v8fp for macro setting
purposes, we don't set a macro yet. Need to ask list
about that.

Refactor: Extract specializing the generic lambda call operator during conversion to fptr deduction into its own function.

No functionality change.

All clang regression tests pass.

Thanks!

Simplify and refactor the uninitialized field warning.

Change the uninitialized field warnings so that field initializers are checked
inside the constructor.  Previously, in class initializers were checked
separately.  Running one set of checks also simplifies the logic for preventing
duplicate warnings.  Added new checks to warn when an uninitialized field is
used in base class initialization.  Also fixed misspelling of uninitialized
and moved all code for this warning together.

Consider used attributes in hidden decls.

Without this patch we would warn and fail to output the function in the test.

Sema: Do not allow lambda expressions to appear inside of constant expressions

We would previously not diagnose this which would lead to crashes (on
very strange code).

This fixes PR17675.

clang-format: Adapt line break penalties for LLVM style.

Specifically make clang-format less eager to break after the opening
parenthesis of a function call.

Before:
  aaaaaaaaaaaaaaaaa(
      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa + aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

After:
  aaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
                        aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
                    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);

Apparently that is preferable. This penalties are adapted
conservatively, we might have to increase them a little bit further.

Add -Wstring-plus-char, which warns when adding char literals to C strings.

Specifically, this warns when a character literal is added (using '+') to a
variable with type 'char *' (or any other pointer to character type). Like
-Wstring-plus-int, there is a fix-it to change "foo + 'a'" to "&foo['a']"
iff the character literal is on the right side of the string.

Patch by Anders Rönnholm!

Just detect a distro as being fedora or not.

We don't have any checks that depend on the version of fedora, so we can
simplify.

Don't check for -L options that gcc doesn't use.

GCC on fedora 18 ARM only uses 2 -L options. Clang prints two extra ones, but
we should not include them in the test as they are not required.
