Before, the note showed the location where you could insert __bridge variants,
but the actual fixit edit came after the cast.

No functionality change.

This was a problem for people who write 'return(result);'

Also fix ARCMT's corresponding code, though there's no test case for this
because implicit casts like this are rejected by the migrator for being
ambiguous, and explicit casts have no problem.

This patch will optimize the following
    movq    %rdi, %rax
    subq    %rsi, %rax
    cmovsq  %rsi, %rdi
    movq    %rdi, %rax
to
    cmpq    %rsi, %rdi
    cmovsq  %rsi, %rdi
    movq    %rdi, %rax

Perform this optimization if the actual result of SUB is not used.

<rdar://problem/11538779> Fixing issues where Python scripts were not able to read user input and/or display output to the user in certain situations - This fix introduces a Python InputReader manager class that mimics the behavior of the interactive interpreter in terms of access to I/O and ensures access to the input and output flows

The commit is intended to fix rdar://11540023.
It is implemented as part of peephole optimization. We can actually implement
this in the SelectionDAG lowering phase.

Bundles should be treated as one atomic transaction when checking
liveness. That is how the register allocator (and VLIW targets) treats
bundles.

The TODOs added to two of the tests are for existing deficiencies in the
typo correction code that could be exposed by using longer identifiers.

that forces all matches to be looked up.  When --all
is not passed, and the current execution frame can
be used to narrow down the search, "target modules
lookup" will try searching in that specific frame
first.  Only if nothing is turned up there will it
go on to search all modules.

This feature is currently enabled only for types.

In addition, I've made the pointer and reference typedef 'void' rather than T*
just so they can't get misused. I would've omitted them entirely but
std::distance likes them to be there even if it doesn't use them.

This rolls back r155808 and r155869.

LLVM is now -Wunused-private-field clean except for
- lib/MC/MCDisassembler/Disassembler.h. Not sure why it keeps all those unaccessible fields.

Add a -rewrite-includes option, which is similar to -rewrite-macros, but only expands #include directives.

obvious stubs. There are dead variables in gtest too, they should be
fixed upstream.

In standard C since C89, a 'translation-unit' is syntactically defined to have
at least one "external-declaration", which is either a decl or a function
definition. In Clang the latter gives us a declaration as well.

The tricky bit about this warning is that our predefines can contain external
declarations (__builtin_va_list and the 128-bit integer types). Therefore our
AST parser now makes sure we have at least one declaration that doesn't come
from the predefines buffer.

Also, remove bogus warning about empty source files. This doesn't catch source
files that only contain comments, and never fired anyway because of our
predefines.
