This is more preparation for multiple different kinds of types from different compilers (clang, Pascal, Go, RenderScript, Swift, etc).

This commit introduces a new enumerator named 'PSVKind' in the
'PseudoSourceValue' class. This enumerator is now used to distinguish between
the various kinds of pseudo source values.
This change is done in preparation for the changes to the pseudo source value
object management and to the PseudoSourceValue's class hierarchy - the next two
PseudoSourceValue commits will get rid of the global variable that manages the
pseudo source values and the mips specific MipsCallEntry subclass.

This commit updates the documentation comments in PseudoSourceValue.cpp and
PseudoSourceValue.h based on the LLVM's documentation style. It also fixes
several instances of variable names that started with a lowercase letter.

object management and to the PseudoSourceValue's class hierarchy.

This commit reformats the files lib/CodeGen/PseudoSourceValue.cpp and

For NVPTX, try to use 32-bit division instead of 64-bit division when the dividend and divisor
fit in 32 bits. This speeds up some internal benchmarks significantly. The underlying reason
is that many index computations are carried out in 64-bits but never actually exceed the
capacity of a 32-bit word.

The issue was we were sending a "qSymbol::" packet and it we were already disconnected were weren't exiting the while loop if we didn't successfully send the qSymbol packet.

emit lexical contents for a declaration for another module. Track which module
those contents came from, and ensure that we only grab the lexical contents
from a single such instantiation.

A global variable "Driver" is to re-entry to the driver to parse a
.drectve section. Because the need is COFF-specific, we don't need
this variable for ELF.

This is the work done by Ryan Brown from http://reviews.llvm.org/D8712 that makes a TypeSystem class and abstracts types to be able to use a type system.
All tests pass on MacOSX and passed on linux the last time this was submitted.

Mangled "linkage" names can be huge, and if the debugger (or other
tools) have no use for them, the size savings can be very impressive
(on the order of 40%).
Add one test for controlling behavior, and modify a number of tests to
either stop using linkage names, or make llc emit them (so these tests
will still run when the default triple is for PS4).

This removes some statistics counters and timers which were not used,
adds new counters and timers for some language features that were not
monitored previously and separates the counters and timers into those
which are of interest for investigating user code and those which are
only of interest to the developer of the runtime itself.
The runtime developer statistics are now ony collected if the
additional #define KMP_DEVELOPER_STATS is set.
Additional user statistics which are now collected include:
* Count of nested parallelism (omp parallel inside a parallel region)
* Count of omp distribute occurrences
* Count of omp teams occurrences
* Counts of task related statistics (taskyield, task execution, task
cancellation, task steal)
* Values passed to omp_set_numtheads
* Time spent in omp single and omp master
None of this affects code compiled without stats gathering enabled,
which is the normal library build mode.
This also fixes the CMake build by linking to the standard c++ library
when building the stats library as it is a requirement. The normal library
does not have this requirement and its link phase is left alone.

`InstCombiner::OptimizeOverflowCheck` was asserting an
invariant (operands to binary operations are ordered by decreasing
complexity) that wasn't really an invariant. Fix this by instead having
`InstCombiner::OptimizeOverflowCheck` establish the invariant if it does
not hold.

Only disable the progress bar when we're generating VS project files,
like we do for XCode. This makes lit use the simple, non-curses progress
bar that looks like this with:
Testing: 0 .. 10.. 20.. 30.. 40.. 50.. 60.. 70.. 80.. 90..

Some of the FP comparisons (ueq, one, ult, ule, ugt, uge) are currently broken, I'll fix them in a follow-up.

ready for a gtest dependency. Reverting to give Manuel some time to look

This non-conforming extension was introduced to make it possible for us
to correctly compile <atomic> in VS 2013 and 2015. Let's limit its
impact to system headers to encourage portable code.

Summary:
For example:
s6 = s0*s5;
s2 = s6*s6 + s6;
...
s4 = s6*s3;
We notice that it is possible for s2 is folded to fma (s0, s5, fmul (s6 s6)).
This only happens when Aggressive is true, otherwise hasOneUse() check
already prevents from folding the multiplication with more uses.

Summary: LowerSwitch crashed with the attached test case after deleting the default block. This happened because the current implementation of deleting dead blocks is wrong. After the default block being deleted, it contains no instruction or terminator, and it should no be traversed anymore. However, since the iterator is advanced before processSwitchInst() function is executed, the block advanced to could be deleted inside processSwitchInst(). The deleted block would then be visited next and crash dyn_cast<SwitchInst>(Cur->getTerminator()) because Cur->getTerminator() returns a nullptr. This patch fixes this problem by recording dead default blocks into a list, and delete them after all processSwitchInst() has been done. It still possible to visit dead default blocks and waste time process them. But it is a compile time issue, and I plan to have another patch to add support to skip dead blocks.
