[InstCombine] Rephrase fix to SimplifyWithOpReplaced
I don't have the IR which is causing the build bot breakage but I can
postulate as to why they are timing out:
1. SimplifyWithOpReplaced was stripping flags from the simplified value.
2. visitSelectInstWithICmp was overriding SimplifyWithOpReplaced because
it's simplification wasn't correct.
3. InstCombine would revisit the add instruction and note that it can
rederive the flags.
4. By modifying the value, we chose to revisit instructions which reuse
the value. One of the instructions is the original select, causing
LLVM to never reach fixpoint.
Instead, strip the flags only when we are sure we are going to perform
the simplification.

InstrProf: Fix reading of consecutive 32 bit coverage maps
When we generate coverage data, we explicitly set each coverage map's
alignment to 8 (See InstrProfiling::lowerCoverageData), but when we
read the coverage data, we assume consecutive maps are exactly
adjacent. When we're dealing with 32 bit, maps can end on a 4 byte
boundary, causing us to think the padding is part of the next record.
Fix this by adjusting the buffer to an appropriately aligned address
between records.
This is pretty awkward to test, as it requires a binary with multiple
coverage maps to hit, so we'd need to check in multiple source files
and a binary blob as inputs.

[CMake] Fixing the check for Ninja
Enabling Ninja Job Pools needs to be dependent on the CMAKE_MAKE_PROGRAM not the CMAKE_GENERATOR. There are generators (like "Sublime Text 2 - Ninja") that also generate ninja build files. Basing of the CMAKE_MAKE_PROGRAM is the best future-proof way to handle this.

[Object, MachO] Cache parsed MachO header in MachOObjectFile. NFC.
Summary:
Avoid parsing object file each time MachOObjectFile::getHeader() is
called. Instead, cache the header in MachOObjectFile constructor, where
it's parsed anyway. In future, we must avoid constructing the object
at all if the header can't be parsed.
Test Plan: regression test suite.

[DAGCombiner] Fix wrong folding of a build_vector into a blend with zero.
Method 'visitBUILD_VECTOR' in the DAGCombiner knows how to combine a
build_vector of a bunch of extract_vector_elt nodes and constant zero nodes
into a shuffle blend with a zero vector.
However, method 'visitBUILD_VECTOR' forgot that a floating point
build_vector may contain negative zero as well as positive zero.
Example:
define <2 x double> @example(<2 x double> %A) {
entry:
%0 = extractelement <2 x double> %A, i32 0
%1 = insertelement <2 x double> undef, double %0, i32 0
%2 = insertelement <2 x double> %1, double -0.0, i32 1
ret <2 x double> %2
}
Before this patch, llc (with -mattr=+sse4.1) wrongly generated
movq %xmm0, %xmm0 # xmm0 = xmm0[0],zero
So, the sign bit of the negative zero was effectively lost.
This patch fixes the problem by adding explicit checks for positive zero.
With this patch, llc produces the following code for the example above:
movhpd .LCPI0_0(%rip), %xmm0
where .LCPI0_0 referes to a 'double -0'.

Fix the check for Ninja in the CMake build.
The current check never passes, because CMAKE_MAKE_PROGRAM, at least on Linux,
includes the full path to the "ninja" binary; this effectively disables
compile/link jobs pools.

Omit unused section symbols from the symbol table.
Section symbols exist as an optimization: instead of having multiple relocations
point to different symbols, many of them can point to a single section symbol.
When that optimization is unused, a section symbol is also unused and adds no
extra information to the object file.
This saves a bit of space on the object files and makes the output of
llvm-objdump -t easier to read and consequently some tests get quite a bit
simpler.
