Comments: [PowerPC] Improve consistency in use of __ppc__, __powerpc__, etc.

Both GCC and LLVM will implicitly define __ppc__ and __powerpc__ for
all PowerPC targets, whether 32- or 64-bit.  They will both implicitly
define __ppc64__ and __powerpc64__ for 64-bit PowerPC targets, and not
for 32-bit targets.  We cannot be sure that all other possible
compilers used to compile Clang/LLVM define both __ppc__ and
__powerpc__, for example, so it is best to check for both when relying
on either inside the Clang/LLVM code base.

This patch makes sure we always check for both variants.  In addition,
it fixes one unnecessary check in lib/Target/PowerPC/PPCJITInfo.cpp.
(At least one of __ppc__ and __powerpc__ should always be defined when
compiling for a PowerPC target, no matter which compiler is used, so
testing for them is unnecessary.)

There are some places in the compiler that check for other variants,
like __POWERPC__ and _POWER, and I have left those in place.  There is
no need to add them elsewhere.  This seems to be in Apple-specific
code, and I won't take a chance on breaking it.

There is no intended change in behavior; thus, no test cases are
added.

Comments: When InstCombine tries to fold away (fsub x, (fneg y)) into (fadd x, y), it is
also worthwhile for it to look through FP extensions and truncations, whose

Comments: Use pipefail when available.

This change makes test with RUN lines like
RUN: opt ... | FileCheck

fail if opt fails, even if it prints what FileCheck wants. Enabling this
found some interesting cases of broken tests that were not being noticed
because opt (or some other tool) was crashing late.

Pipefail is used when the shell supports it or when using the internal
python based tester.Properties:

Comments: SimplifyCFG: Use parallel-and and parallel-or mode to consolidate branch conditions

Merge consecutive if-regions if they contain identical statements.
Both transformations reduce number of branches.  The transformation
is guarded by a target-hook, and is currently enabled only for +R600,
but the correctness has been tested on X86 target using a variety of
CPU benchmarks.

Comments: clang-cl: add support for the /? and /help options

This establishes a new Flag in Options.td, which can be assigned to
options that should be made available in clang's cl.exe compatible
mode, and updates the Driver to make use of the flag.

(The whitespace change to CMakeLists forces the build to re-run CMake
 and pick up the include dependency on the new .td file. This makes the
 build work if someone moves backwards in commit history after this change.)

to the visitor based analysis system as it removes one entire use-list
