BlockGenerators: Replace getNewScalarValue with getNewValue
Both functions implement the same functionality, with the difference that
getNewScalarValue assumes that globals and out-of-scop scalars can be directly
reused without loading them from their corresponding stack slot. This is correct
for sequential code generation, but causes issues with outlining code e.g. for
OpenMP code generation. getNewValue handles such cases correctly.
Hence, we can replace getNewScalarValue with getNewValue. This is not only more
future proof, but also eliminates a bunch of code.
The only functionality that was available in getNewScalarValue that is lost
is the on-demand creation of scalar values. However, this is not necessary any
more as scalars are always loaded at the beginning of each basic block and will
consequently always be available when scalar stores are generated. As this was
not the case in older versions of Polly, it seems the on-demand loading is just
some older code that has not yet been removed.
Finally, generateScalarLoads also generated loads for values that are loop
invariant, available in GlobalMap and which are preferred over the ones loaded
in generateScalarLoads. Hence, we can just skip the code generation of such
scalar values, avoiding the generation of dead code.

[MS Compat] Don't crash if __GetExceptionInfo is in global scope
__GetExceptionInfo triggered Sema::LazilyCreateBuiltin which tries to
create a non-templated function decl. This is unnecessary and
ill-advised, there is no need for us to create a declaration for such a
builtin.
This fixes PR26298.

Write the session log file in UTF-8.
Previously we were writing in the default encoding, which depends
on the operating system and is not guaranteed to be unicode aware.
On Python 3, this would lead to a situation where writing unicode
text to the log file generates an exception. The fix here is to
write session logs using the proper encoding, which incidentally
fixes another test, so xfail is removed from that.

Set symbol types for function symbols loaded from PE/COFF
This fixes the regression of several tests on Windows after rL258621.
The root problem is that ObjectFilePECOFF was not setting type information for the symbols, and the new CL rejects symbols without type information, breaking functionality like thread step-over.
The fix sets the type information for functions (and creates a TODO for other types).
Along the way, I fixed some typos and formatting that made the code I was debugging harder to understand.
In the long run, we should consider replacing most of ObjectFilePECOFF with the COFF parsing code from LLVM.

Sort intrinsics by LLVM intrinsic name, rather than tablegen def name
Step one towards using a simple binary search to lookup intrinsic IDs
instead of our crazy table generated switch+memcmp+startswith code that
makes Function.cpp take about a minute to compile. See PR24785 and
PR11951 for why we should do this.
The X86 backend contains tables that need to be sorted on intrinsic ID,

LiveIntervalAnalysis: Cleanup handleMove{Down|Up}() functions, NFC
These two functions are hard to reason about. This commit makes the code
more comprehensible:
- Use four distinct variables (OldIdxIn, OldIdxOut, NewIdxIn, NewIdxOut)
with a fixed value instead of a changing iterator I that points to
different things during the function.
- Remove the early explanation before the function in favor of more
detailed comments inside the function. Should have more/clearer comments now
stating which conditions are tested and which invariants hold at
different points in the functions.
The behaviour of the code was not changed.
I hope that this will make it easier to review the changes in
http://reviews.llvm.org/D9067 which I will adapt next.

This patch teaches MC to use .p2align instead of .align, so that people reading

Fix some issues with bytes and strings in Python 3.
SBProcess::ReadMemory and other related functions such as
WriteMemory are returning Python string() objects. This means
that in Python 3 that are returning Unicode objects. In reality
they should be returning bytes objects which is the same as a string
in Python 2, but different in Python 3. This patch updates the
generated SWIG code to return Python bytes objects for all
memory related functions.
One quirk of this patch is that the C++ signature of ReadCStringFromMemory
has it writing c-string data into a void*. This confuses our swig
typemaps which expect that a void* means byte data. So I hacked up
a custom typemap which maps this specific function to treat the
void* as string data instead of byte data.

In Python 2 this was easy because bytes and strings are the same thing,

to mix raw Python C API code with PythonDataObjects code, I've also
introduced a PythonByteArray class to PythonDataObjects to make the
