If we had the regular expression "\b" in FileCheck like Perl...

 - The only group where it makes sense for the "ExternC" bit is System, so this
   simplifies having to have the extra isCXXAware (or ImplicitExternC, depending
   on what code you talk to) bit caried around.

llvm-svn: 173859

Cleaned up the objective C name parsing code to use a class.

Now breakpoints that are set by name that are objective C methods without the leading '+' or '-' will resolve. We do this by expanding all the objective C names for a given string. For example:

(lldb) b [MyString cStringUsingEncoding:]

Will set a breakpoint with multiple possible names: 
-[MyString cStringUsingEncoding:]
+[MyString cStringUsingEncoding:]

Also if you have a category, it will strip the category and set a breakpoint in all variants:

(lldb) [MyString(my_category) cStringUsingEncoding:]

Will resolve to the following names:

-[MyString(my_category) cStringUsingEncoding:]
+[MyString(my_category) cStringUsingEncoding:]
-[MyString cStringUsingEncoding:]
+[MyString cStringUsingEncoding:]

Likewise when we have:

(lldb) b -[MyString(my_category) cStringUsingEncoding:]

It will resolve to two names:
-[MyString(my_category) cStringUsingEncoding:]
-[MyString cStringUsingEncoding:]

 - This slightly decouples the path handling, since before the group sometimes
   dominated the "use sysroot" bit, but it was still passed in via the API.

 - No functionality change.

Changing ARMBaseTargetMachine to return ARMTargetLowering intead of
the generic one (similar to x86 code).

Tests showing which instructions were added to cast when necessary
or cost zero when not. Downcast to 16 bits are not lowered in NEON,
so costs are not there yet.

implementation; this is much more inline with the original implementation
(i.e., pre-ubsan) and does not require run-time library support.

The trapping implementation can be invoked using either '-fcatch-undefined-behavior'
or '-fsanitize=undefined-trap -fsanitize-undefined-trap-on-error', with the latter
being preferred.  Eventually, the -fcatch-undefined-behavior' flag will be removed.

Added some periods to some comments and added an overload for operator<< for type Sequence so I can print out Sequences in debug statements.

No functional changes. Also removed experimental-warning from all of
clang-format's files, as it is no longer accurate.

Changed DoesObjCBlockEscape => DoesRetainableObjPtrEscape so I can use it to perform escape analysis of other retainable object pointers in other locations.

even if they came from a macro expansion.

This fixes an issue where a GUID passed as macro argument ends up
malformed after preprocessing because we added spaces inside it.

The diagnostics generation isn't designed for this use case, so add a note to
fix this in the very near future.  For now, just generated the diagnostics for
the first failing command.

Before:
aaaaaaa(aaaaaa( // comment
                aaaaaaa));
<big mess>

After:
aaaaaaa(aaaaaa( // comment
    aaaaaaaa));
function(/* parameter 1 */ aaaaaaa,
         /* parameter 2 */ aaaaaaa,
         /* parameter 3 */ aaaaaaa,
         /* parameter 4 */ aaaaaaa);

(the latter example was only wrong in the one-arg-per-line mode, e.g. in
Google style).
