Re-commit r191910 (reverted in r191936) with layering violation fixed, by
moving the bug categories to StaticAnalyzerCore instead of ...Checkers.

It looks like clang always produce code with the ieee comparisons, so it is
safe to ignore this flag (we still error on -mno-ieee-fp).

One small functionality change is to bring the sizeof-pointer checker in
line with the other checkers by making its category be "Logic error"
instead of just "Logic". There should be no other functionality changes.

This partially addresses PR17435, but it doesn't actually implement the
pragma. If we implement it, we should map levels 1-4 to something like
-Wall and level 0 to something like -w.

This attribute allows users to use a modified C or C++ function as an ARM
exception-handling function and, with care, to successfully return control to
user-space after the issue has been dealt with.

When we check access for lookup results, make sure we propagate the
result's access to the access control APIs; this can be different from
the natural access of the declaration depending on the path used by the lookup.

The help text for clang-format's -style option and the function that processes
its value is moved to libFormat in this patch. The goal is to enable other
tools that use libFormat and also have a -style option to behave consistently
with clang-format.

such option I've been able to find in the wild in our build system.
Note that I haven't added test cases for this. I can do so if folks
want, but they're *really* boring considering that this is all generated
code to parse and ignore unsued options.

As Richard pointed out to me, dyn_cast is very cheap - there is no real benefit from adding cluttery overloads to only avoid that cast.
No functionality change.

The general strategy is to create template versions of the conversion function and static invoker and then during template argument deduction of the conversion function, create the corresponding call-operator and static invoker specializations, and when the conversion function is marked referenced generate the body of the conversion function using the corresponding static-invoker specialization. Similarly, Codegen does something similar - when asked to emit the IR for a specialized static invoker of a generic lambda, it forwards emission to the corresponding call operator.
This patch has been reviewed in person both by Doug and Richard. Richard gave me the LGTM.
A few minor changes:
- per Richard's request i added a simple check to gracefully inform that captures (init, explicit or default) have not been added to generic lambdas just yet (instead of the assertion violation).
- I removed a few lines of code that added the call operators instantiated parameters to the currentinstantiationscope. Not only did it not handle parameter packs, but it is more relevant in the patch for nested lambdas which will follow this one, and fix that problem more comprehensively.
- Doug had commented that the original implementation strategy of using the TypeSourceInfo of the call operator to create the static-invoker was flawed and allowed const as a member qualifier to creep into the type of the static-invoker. I currently kludge around it - but after my initial discussion with Doug, with a follow up session with Richard, I have added a FIXME so that a more elegant solution that involves the use of TrivialTypeSourceInfo call followed by the correct wiring of the template parameters to the functionprototypeloc is forthcoming.
Thanks!

- We scan for whitespace between comments anyways, remember any newlines seen
along the way.
- Use this newline number to decide whether two comments are adjacent.
- Since the newline check is now free remove the caching and unused code.
- Remove unnecessary boolean state from the comment list.
- No behavioral change.

...rather than trying to figure it out from the call site, and having
people complain that we guessed wrong and that a prototype-less call is
the same as a variadic call on their system. More importantly, fix a
crash when there's no decl at the call site (though we could have just
returned a default value).

This motion appears to have consensus in the C++ committee and is
expected to be voted into the C++14 draft tomorrow during the formal
vote.
No extension warning in C++11 as attributes not specified in the
standard using the standard syntax in C++11 have implementation defined
meaning, and we define the meaning proposed for C++14.
There is one bug exposed as we do not warn on a deprecated template
specialization. I've left a FIXME in the test case and will dig into
that next.
Also, I will add a few more exhaustive test cases of the other features
specified for this attribute in a follow-up commit.

The vector version of shiftedCodePosition() requires Replacements to be
in sorted order.
Turned existing comment about sorting for deduplicate() into an exact

- We really shouldn't compute line numbers for every file that is asked if it's
the main file, it destroys the lazy computation.
- Invalid locations are no longer accounted to the main file, no other
functionality change.

Summary:
Changed UseTab to be a enum with three options: Never, Always,
ForIndentation (true/false are still supported when reading .clang-format).
IndentLevel should currently be propagated correctly for all tokens, except for
block comments. Please take a look at the general idea before I start dealing
with block comments.

The intent of getTypeOperand() was to yield an unqualified type.
However QualType::getUnqualifiedType() does not strip away qualifiers on
arrays.
N.B. This worked fine when typeid() was applied to an expression
because we would inject as implicit cast to the unqualified array type
in the AST.

The previous change caused the driver to translate -Wa,-L to the
-msave-temp-labels option for cc1as, but cc1as did not accept that option.
This patch follows the same approach used for similar options (-relax-all,
-noexecstack) in the previous patch.
