Turns out `parseBitcodeFile()` does *not* take ownership of the buffer.
This was already clear in the header docs, but I obviously didn't read
them (having noticed that it gets stored in a `unique_ptr<>`).

As defined in the SPIR 1.2 specification, this node behaves similarly to
kernel_arg_type but will print the underlying type name, e.g., without
typedefs.
Example:
typedef unsigned int myunsignedint;
would report:
'myunsignedint' in the kernel_arg_type node
'uint' in the kernel_arg_base_type node

a) add SKX support to Clang driver;
b) add tests for SKX target and AVX512BW, AVX512DQ, AVX512VL features into clang driver tests

This fixes a bug where kernel_arg_type was always changing 'unsigned ' to 'u'
for any parameter type, including non-canonical types.
Example:
typedef unsigned int myunsignedint;
would report:
"myunt"

Iterator invalidation issues already force us to do one lookup and one
insert.
Don't use the particular bit-pattern of the 'Align' field to determine
whether or not we have already inserted into the TypeInfo DenseMap;
instead ask for an iterator to the TypeInfo entry.

MaterializeTemporaryExpr already contains information about the lifetime
of the temporary; if the lifetime is not the full statement, we do not
want to emit a destructor at the end of the full statement for it.

A templated using declaration may be used as a template-template
argument.
Unfortunately, the VS "14" chooses '?' as the sole marker for the
argument. This is problematic because it presupposes the possibility of
using more than one template-aliases as arguments to the same template.
This fixes PR20047.

the jump instruction table pass. First, the verifier is already built
into all the tools. The test case is adapted to just run llvm-as
demonstrating that we still catch the broken module. Second, the
verifier is *extremely* slow. This was responsible for very significant
compile time regressions.
If you have deployed a Clang binary anywhere from r210280 to this
commit, you really want to re-deploy.

We now (1) correctly decode the branch immediate, (2) modify the immediate to
corretly treat it as PC-rel, and (3) properly populate the stub entry.
Previously we had been doing each of these wrong.

neverHasSideEffects is deprecated, and hasSideEffects = 0 is already
set on the base classes of the basic ALU instruction classes. The
base classes also already set mayLoad = 0 and mayStore = 0

This object is used to encapsulate all actions that need to be
done before/after printing UBSan diagnostics. Currently these
actions are:
* locking a mutex to ensure that UBSan diagnostics from several
threads won't mix with each other and with other sanitizers'
reports
* killing a program once the report is printed (if necessary).
Use this object in all UBSan handlers. Unify the way we implement
fatal and non-fatal handlers by making all the handlers simple
one-liners that redirect __ubsan_handle_foo(_abort)? to
handleFooImpl().

In some cases the address of a function will be materialized with a movw/movt
pair. If the function is a thumb function, the low bit needs to be set on
the movw immediate value.

The MS ABI has a notion of 'required alignment' for fields; this
alignment supercedes pragma pack directives.
MSVC takes into account alignment attributes on typedefs when
determining whether or not a field has a certain required alignment.
Do the same in clang by tracking whether or not we saw such an attribute
when calculating the type's bitwidth and alignment.
This fixes PR20418.

This commit fixes undefined behaviour that caused the revert in r214249.
The problem was two unsequenced operations on a `DenseMap<>`, giving
different behaviour in GCC and Clang. This:
DenseMap<T*, unsigned> DM;
for (auto &X : ...)
DM[&X] = DM.size() + 1;
should have been:
DenseMap<T*, unsigned> DM;
for (auto &X : ...) {
unsigned Size = DM.size();
DM[&X] = Size + 1;
}
Until r214242, this difference between compilers didn't matter. In
r214242, `OrderMap::LastGlobalValueID` was introduced and compared
against IDs, which in GCC were off-by-one my expectations.

We can treat ds_read2_* as a single offset if the offsets are adjacent.
No test since emission of read2 instructions for partially
aligned loads isn't implemented yet.

The -sectalign option is used to increase the alignment required for a section.
It required some reworking of how the __TEXT segment is laid out because that
segment also contains the mach_header and load commands. And the size of load
commands depend on the number of segments, sections, and dependent dylibs used.
Using this option will simplify some future test cases because the final
address of code can be pinned down, making tests of its content easier.

Fix the missing case in ScalarizeVectorResult() that was exposed with
