[opaque pointer type] Allow gep_type_iterator to work with the pointee type from the GEP instruction
The raw non-instruction/constant form of this is still relying on being
able to access the pointee type from a pointer type - those will be
cleaned up later. For now, just focus on the cases where the pointee
type is easily accessible.

Resubmit r237708 (MIR Serialization: print and parse LLVM IR using MIR format).
This commit is a 2nd attempt at committing the initial MIR serialization patch.
The first commit (r237708) made the incremental buildbots unstable and was
reverted in r237730. The original commit didn't add a terminating null
character to the LLVM IR source which was passed to LLParser, and this
sometimes caused the test 'llvmIR.mir' to fail with a parsing error because
the LLVM IR source didn't have a null character immediately after the end
and thus LLLexer encountered some garbage characters that ultimately caused
the error.
This commit also includes the other test fixes I committed in
r237712 (llc path fix) and r237723 (remove target triple) which
also got reverted in r237730.
--Original Commit Message--
MIR Serialization: print and parse LLVM IR using MIR format.
This commit is the initial commit for the MIR serialization project.
It creates a new library under CodeGen called 'MIR'. This new
library adds a new machine function pass that prints out the LLVM IR
using the MIR format. This pass is then added as a last pass when a
'stop-after' option is used in llc. The new library adds the initial
functionality for parsing of MIR files as well. This commit also
extends the llc tool so that it can recognize and parse MIR input files.

llvm-svn: 237954
Added a new command in ProcessGDBRemote that can figure out the performance characterisitics of your GDB remote server.
To addess this, attach to any GDB server and when stopped type:
(lldb) process plugin packet speed-test
The default will send a variety of packets with different amounts of data to send/receive and print the performance of each packet type:
Testing sending 1000 packets of various sizes:
qSpeedTest(send=0 , recv=0 ) in 0.
057837000 sec for 17289.97 packets/sec ( 0.057837 ms per packet) with standard deviation of 0.007705 ms
qSpeedTest(send=0 , recv=4 ) in 0.
056162000 sec for 17805.63 packets/sec ( 0.056162 ms per packet) with standard deviation of 0.004439 ms
qSpeedTest(send=0 , recv=8 ) in 0.
057687000 sec for 17334.93 packets/sec ( 0.057687 ms per packet) with standard deviation of 0.008135 ms
qSpeedTest(send=0 , recv=16 ) in 0.
058547000 sec for 17080.29 packets/sec ( 0.058547 ms per packet) with standard deviation of 0.005884 ms
qSpeedTest(send=0 , recv=32 ) in 0.
058289000 sec for 17155.89 packets/sec ( 0.058289 ms per packet) with standard deviation of 0.004057 ms
qSpeedTest(send=0 , recv=64 ) in 0.
061324000 sec for 16306.83 packets/sec ( 0.061324 ms per packet) with standard deviation of 0.010838 ms
qSpeedTest(send=0 , recv=128 ) in 0.
065688000 sec for 15223.48 packets/sec ( 0.065688 ms per packet) with standard deviation of 0.006997 ms
qSpeedTest(send=0 , recv=256 ) in 0.
070621000 sec for 14160.09 packets/sec ( 0.070621 ms per packet) with standard deviation of 0.006188 ms
qSpeedTest(send=0 , recv=512 ) in 0.
086738000 sec for 11528.97 packets/sec ( 0.086738 ms per packet) with standard deviation of 0.007867 ms
qSpeedTest(send=0 , recv=1024 ) in 0.
146375000 sec for 6831.77 packets/sec ( 0.146375 ms per packet) with standard deviation of 0.010313 ms
qSpeedTest(send=4 , recv=0 ) in 0.
057807000 sec for 17298.94 packets/sec ( 0.057807 ms per packet) with standard deviation of 0.009702 ms
....
It will then also use various sizes to receive 4MB of data from the GDB server and print out the stats:
Testing receiving 4.0MB of data using varying receive packet sizes:
qSpeedTest(send=0 , recv=32 ) 131072 packets needed to receive 4.0MB in 7.
721290000 sec for 0.518048 MB/sec for 16975.40 packets/sec ( 0.058909 ms per packet)
qSpeedTest(send=0 , recv=64 ) 65536 packets needed to receive 4.0MB in 4.
029236000 sec for 0.992744 MB/sec for 16265.12 packets/sec ( 0.061481 ms per packet)
qSpeedTest(send=0 , recv=128 ) 32768 packets needed to receive 4.0MB in 2.
233854000 sec for 1.790627 MB/sec for 14668.82 packets/sec ( 0.068172 ms per packet)
qSpeedTest(send=0 , recv=256 ) 16384 packets needed to receive 4.0MB in 1.
160024000 sec for 3.448204 MB/sec for 14123.84 packets/sec ( 0.070802 ms per packet)
qSpeedTest(send=0 , recv=512 ) 8192 packets needed to receive 4.0MB in 0.
701603000 sec for 5.701230 MB/sec for 11676.12 packets/sec ( 0.085645 ms per packet)
qSpeedTest(send=0 , recv=1024 ) 4096 packets needed to receive 4.0MB in 0.
596786000 sec for 6.702570 MB/sec for 6863.43 packets/sec ( 0.145700 ms per packet)
There is a JSON mode so we can use this in the test suite to track GDB server performance for each platform:

[PPC/LoopUnrollRuntime] Don't avoid high-cost trip count computation on the PPC/A2
On X86 (and similar OOO cores) unrolling is very limited, and even if the
runtime unrolling is otherwise profitable, the expense of a division to compute
the trip count could greatly outweigh the benefits. On the A2, we unroll a lot,
and the benefits of unrolling are more significant (seeing a 5x or 6x speedup
is not uncommon), so we're more able to tolerate the expense, on average, of a
division to compute the trip count.

Don't import module `lock` at global scope.
`lock` depends on `fcntl`, which doesn't exist on Windows. Until
someone implements an equivalent locking mechanism on Windows, we
can't have lock imported globally.

writeSymbolTable now only needs a MCContext.

Pass a const MCAssembler to writeSectionHeader.
It never creates sections, so it can use Asm.getSectionData instead of
Asm.getOrCreateSectionData.

YAML: Null terminate block scalar's value.
The commit null terminates the string value in the `yaml::BlockScalarNode`
class.
This change is motivated by the initial MIR serialization commit (r237708)
that I reverted in r237730 because the LLVM IR source from the block
scalar node wasn't terminated by a null character and thus the buildbots
failed on one testcase sometimes. This change enables me to recommit
the reverted commit.

Fix StreamingMemoryObject to respect known object size.
The existing code for method StreamingMemoryObject.fetchToPos does not respect
the corresonding call to setKnownObjectSize(). As a result, it allows the
StreamingMemoryObject to read bytes past the object size.
This patch provides a test case, and code to fix the problem.

Fetch alignment directly out of MCSection. NFC.

Move alignment from MCSectionData to MCSection.
This starts merging MCSection and MCSectionData.
There are a few issues with the current split between MCSection and
MCSectionData.
* It optimizes the the not as important case. We want the production
of .o files to be really fast, but the split puts the information used
for .o emission in a separate data structure.
* The ELF/COFF/MachO hierarchy is not represented in MCSectionData,
leading to some ad-hoc ways to represent the various flags.
* It makes it harder to remember where each item is.
The attached patch starts merging the two by moving the alignment from
MCSectionData to MCSection.
Most of the patch is actually just dropping 'const', since
MCSectionData is mutable, but MCSection was not.

Only check for matching arch and UUID when looking for dsym in vincinity of executable.
ModuleSpecs::FindMatchingModuleSpec looks for matching filenames but when
looking for the dSYM we should only be looking for a matching architecture and
and UUID. Jason pointed out this mistake in http://reviews.llvm.org/D9174 when
this function was incorrectly converted to not be Mac specific.
Test Plan:
Running LLDB on test/lang/c/shared_lib_stripped_symbols/a.out in a debugger I've
verified LocateDSYMInVincinityOfExecutable correctly locates the matching dSYM.

[clang-tidy] Disable google-readability-casting for .c files and their headers.
Some people have reasons to compile their .c files as C++ in some configurations

AVX-512: Enabled SSE intrinsics on AVX-512.
Predicate UseAVX depricates pattern selection on AVX-512.
This predicate is necessary for DAG selection to select EVEX form.
But mapping SSE intrinsics to AVX-512 instructions is not ready yet.
So I replaced UseAVX with HasAVX for intrinsics patterns.
