Benjamin Kramer 47c4d101e0 [clang-tidy] Add a checker that removes deducible arguments from std::make_pair
Those may be incompatible with C++11 and are unnecessary. We suggest
removing the template arguments when they match the types of the make_pair
arguments or replace it with std::pair and explicit template arguments when
not.

Now, this can be properly formatted:

Before, clang-format could end up, not formatting the code at all.

Matt Arsenault ca3976f7ae R600: Add dag combine for copy of an illegal type.
This helps avoid redundant instructions to unpack, and repack
the vectors. Ideally we could recognize that pattern and eliminate
it. Currently v4i8 and other small element type vectors are scalarized,
so this has the added bonus of avoiding that.

Greg Clayton 45a44f3c4d Any commands that are executed through the public interface using SBCommandInterpreter::HandleCommand() are assumed to be in non-interactive mode.
Any commands that want interactivity (stdin) will need to be executed through the normal command interpreter using the debugger's in/out/err file handles, or by using "command source".

Individual commands through the API will have their STDIN disabled. The STDOUT and STDERR will be redirected into the SBCommandReturnObject argument to SBCommandInterpreter::HandleCommand() as usual.

This helps with a deadlock situation in an IDE (Xcode) where the IDE was managing the breakpoint actions by setting a breakpoint callback and doing things manually.

Andrea Di Biagio 2152a6c78b [DAGCombiner] Avoid calling method 'isShuffleMaskLegal' on illegal vector types.
This patch fixes a crasher in method 'DAGCombiner::visitOR' due to an invalid
call to method 'isShuffleMaskLegal'. On x86, method 'isShuffleMaskLegal'
always expects a legal vector value type in input.

With this patch, we immediately check if the input OR dag node has a legal
vector type; we only try to fold a OR dag node into a single shufflevector
if we know that the resulting shuffle will have a legal type.
This is to avoid calling method 'isShuffleMaskLegal' on a potentially
illegal vector value type.

Added a new test-case to file 'CodeGen/X86/combine-or.ll' to verify that
DAGCombiner doesn't crash in the attempt to check/combine an OR between shuffles
with illegal types.
