If we use a pair with an enum type this could create values outside
of the enum range. Avoid it by creating the bit pattern directly.
While there turn a dynamic assert into a static one. No functionality
change.

Utilize the previous move of MVT to a separate header for all trivial
cases (that don't need any further restructuring).

Since our error_category is based on the std one, we should have the
same visibility for the constructor. This also allows us to avoid
using the _do_message implementation detail in our own categories.

Microsoft PE/COFF Spec clearly states that the field is of signed interger
type. However, in reality, it's unsigned. If cl.exe needs to create a large
number of sections for COMDAT sections, it will just create more than 32768
sections. Handling large section number as negative number is not correct.
I think this is a spec bug.

based on the ODR.
This adds an OdrMemberMap to DwarfDebug which is used to unique C++
member function declarations based on the unique identifier of their
containing class and their mangled name.
We can't use the usual DIRef mechanism here because DIScopes are indexed
using their entire MDNode, including decl_file and decl_line, which need
not be unique (see testcase).
Prior to this change multiple redundant member function declarations would
end up in the same uniqued DW_TAG_class_type.

For better or worse, this is currently the normal error reporting path
when dealing with backend errors from inline assembly. It's not just
internal compiler issues that come through here, so we shouldn't be
creating a backtrace on this path.

Summary:
The sample profiler pass emits several error messages. Instead of
just aborting the compiler with report_fatal_error, we can emit
better messages using DiagnosticInfo.
This adds a new sub-class of DiagnosticInfo to handle the sample
profiler.

any lexical scopes then go ahead and turn on DW_AT_ranges for the
compile unit since we would be claiming to describe in the CU
a range for which we don't have information in the CU otherwise.

This sometimes remains null into MCLineTableHeader::Emit where we
conditionally construct a label if one isn't provided for us. We need it
to remain null (rather than just always constructing the label) so we
can identify unused line tables... which is a bit weird and maybe we can
do away with that logic one day (& on that day we can always construct
the label up-front and just have compilation units query the line table
for its label, etc)

This change brings getCallPreservedMask()'s logic in line with
getCalleeSavedRegs().
While this changes the control flow slightly, the change is not
currently observable. is64Bit must be false to get to the accidental
fallthrough, but the case that we fall into (coldcc) does nothing unless
is64Bit is true.

sys::fs::createUniqueFile returns an absolute path, so MakeSharedObject does

The idea behind this split of ValueTypes.h, is to make it easier to
ensure that stuff after type legalization only use MVT (rather than
EVT), by watching include dependencies.

Commit r181723 introduced code to avoid placing initialized variables
needing relocations into the .rodata section, which avoid copy relocs
that do not work as expected on ppc64 function references.
The same treatment is also needed for *named* .rodata.XXX sections.
This patch changes PPC64LinuxTargetObjectFile::SelectSectionForGlobal
to modify "Kind" *before* calling the default SelectSectionForGlobal
routine, instead of first calling the default routine and then just
checking for the (main) .rodata section afterwards.
