Daniel Jasper 922349cdba clang-format: Don't merge simple blocks in case statements.
Before:

Saleem Abdulrasool 79ed5d44e7 Basic: rename VisualStudio to Windows
Visual Studio is the Integrated Development Environment.  The toolchain is
generally referred to MSVC.  Rename the target information to be more precise as
per the recommendation of Reid Kleckner.

Richard Trieu 0f09774f17 Extend -Wtautological-constant-out-of-range-compare to handle boolean values
better.  This warning will now trigger on the following conditionals:

bool b;
int i;

if (b > 1) {}  // always false
if (0 <= (i > 5)) {} // always true
if (-1 > b) {} // always false

Saleem Abdulrasool 324a103619 sweep up -Wformat warnings from gcc
This is a purely mechanical change explicitly casting any parameters for printf
style conversion.  This cleans up the warnings emitted by gcc 4.8 on Linux.

Justin Bogner f3aefca7c1 CodeGen: Don't create branch weight metadata from empty profiles
If all of our weights are zero when calculating branch weights, it
means we haven't profiled the code in question. Avoid creating a
metadata node that says all branches are equally likely in this case.

The test also checks constructs that hit the other createBranchWeights
overload. These were already working.

Reid Kleckner 9307fba85d Add clang-cl alias to allow users to disable c4005
If we ever want three or more aliases, at that point we should put MSVC
warning ids in DiagnosticGroups.td.  We can use that to support #pragma
warning.

Rui Ueyama 9457510abf Fix ELFFileNode::resetNextIndex().
ELFLinkingContext has a method addUndefinedAtomsFromSharedLibrary().
The method is being used to skip a shared library within --start-group
and --end-group if it's not the first iteration of the group.

We have the same, incomplete mechanism to skip a shared library within
a group too. That's implemented in ELFFileNode. It's intended to not
return a shared library on the second or further iterations in the
first place. This mechanism is preferred over
addUndefinedAtomsFromSharedLibrary because the policy is implemented
in Input Graph -- that's what Input Graph is for.

This patch removes the dupluicate feature and fixes ELFFileNode.

Lang Hames cb74fa696b [ARM64] Teach the ARM64DeadRegisterDefinition pass to respect implicit-defs.
When rematerializing through truncates, the coalescer may produce instructions
with dead defs, but live implicit-defs of subregs:
E.g.
  %X1<def,dead> = MOVi64imm 2, %W1<imp-def>; %X1:GPR64, %W1:GPR32

These instructions are live, and their definitions should not be rewritten.
