This is important because of different addressing modes
depending on the address space for GPU targets.
This only adds the argument, and does not update
any of the uses to provide the correct address space.

This change produces a dynamic library named libomp instead of
libiomp5. Similar to the CMake change, it produces symlinks of libiomp5
in the exports/ directory for Unix systems and copies for Windows.

Alternatively, this type could be derived on-demand whenever
getResultElementType is called - if someone thinks that's the better
choice (simple time/space tradeoff), I'm happy to give it a go.

This change has the CMake build system create a dynamic library named
libomp instead of libiomp5. Also any reference to libiomp is replaced
with libomp. One can still use the LIBOMP_LIB_NAME variable to enforce
a different name, and everything will still work as expected. An important
note is that libiomp5 and libgomp symlinks are created at install time when
on Unix systems. On Windows, copies are created with the legacy names.

Instead of returning non-categorized errors, return categorized errors.
All uses of make_dynamic_error_code are removed.
Because we don't have error reporting mechanism, I just chose to print out
error messages to stderr, and then return an error object. Not sure if
that's the right thing to do, but at least it seems practical.

These changes are mostly in comments, but there are a few
that aren't. Change libiomp5 => libomp everywhere. One internal
function name is changed in kmp_gsupport.c, and in kmp_i18n.c, the
static char[] variable 'name' is changed to "libomp".

There is no MCSectionData, so the old name is now meaningless.
Also remove some asserts/checks that were there just because the information
they used was in MCSectionData.

Unreachable values may use themselves in strange ways due to their
dominance property. Attempting to translate through them can lead to
infinite recursion, crashing LLVM. Instead, claim that we weren't able
to translate the value.
This fixes PR23096.

This fixes a bug in the line info handling in the dwarf code, based on a
problem I when implementing RelocVisitor support for MachO.
Since addr+size will give the first address past the end of the function,
we need to back up one line table entry. Fix this by looking up the
end_addr-1, which is the last address in the range. Note that this also
removes a duplicate output from the llvm-rtdyld line table dump. The
relevant line is the end_sequence one in the line table and has an offset
of the first address part the end of the range and hence should not be
included.
Also factor out the common functionality into a separate function.
This comes up on MachO much more than on ELF, since MachO
doesn't store the symbol size separately, hence making
said situation always occur.

Previously, this feature was implemented using a special type of
undefined symbol, in addition to an intricate way to make the resolver
read a virtual file containing that renaming symbols.
Now the feature is directly handled by the symbol table.
The symbol table has a function, rename(), to rename symbols, whose
definition is 4 lines long. Symbol renaming is naturally modeled using
Symbol and SymbolBody.

Previously, a MemoryBuffer of a file was owned by each InputFile object.
This patch makes the Driver own all of them. InputFiles now have only
MemoryBufferRefs. This change simplifies ownership managment
(particularly for ObjectFile -- the object owned a MemoryBuffer only when
it's not created from an archive file, because in that case a parent
archive file owned the entire buffer. Now it owns nothing unconditionally.)

New MipsAbiInfoHandler merges and hold both ELF header flags
and registries usage masks. In the future commits it will manage some
additional information.

It does not involve notions of virtual archives or virtual files,
nor store a list of undefined symbols somewhere else to consume them later.
We did that before. In this patch, undefined symbols are just added to
the symbol table, which now can be done in very few lines of code.
