Rename some member variables from TD to DL.

TargetData was renamed DataLayout back in r165242.

[mips] Add support for ELF64-mips and the R_MIPS_32/R_MIPS_64 relocs for it.

Summary:
This fixes several test failures when building LLVM on a MIPS host.

The failures were:
    LLVM :: DebugInfo/enum.ll
    LLVM :: DebugInfo/inlined-arguments.ll
    LLVM :: DebugInfo/member-order.ll
    LLVM :: DebugInfo/namespace.ll
    LLVM :: DebugInfo/template-recursive-void.ll
    LLVM :: DebugInfo/tu-composite.ll
    LLVM :: DebugInfo/two-cus-from-same-file.ll
    LLVM :: Linker/type-unique-simple-a.ll
    LLVM :: Linker/type-unique-simple2.ll

[AArch64] Expanded sin, cos, pow with FP vector types inputs

Consistently check 'IsCode' when allocating sections in RuntimeDyld (via
findOrEmitSection).

Vaidas Gasiunas's patch, r201259, fixed one instance where we were always
allocating sections as text. This patch fixes the remaining buggy call sites.

No test case: This isn't breaking anything that I know of, it's just
inconsistent.

Rename a DebugLoc variable to DbgLoc and a DataLayout to DL.

This is quiet a bit less confusing now that TargetData was renamed DataLayout.

Fix PR18743.

The IR
@foo = private constant i32 42

is valid, but before this patch we would produce an invalid MachO from it. It
was invalid because it would use an L label in a section where the liker needs
the labels in order to atomize it.

One way of fixing it would be to just reject this IR in the backend, but that
would not be very front end friendly.

What this patch does is use an 'l' prefix in sections that we know the linker
requires symbols for atomizing them. This allows frontends to just use
private and not worry about which sections they go to or how the linker handles
them.

One small issue with this strategy is that now a symbol name depends on the
section, which is not available before codegen. This is not a problem in
practice. The reason is that it only happens with private linkage, which will
be ignored by the non codegen users (llvm-nm and llvm-ar).

[docs] Nuke some references to llvm-gcc

From a cursory look it seems like all the described commandline options
and such apply to clang just fine, but I'd appreciate a second opinion.

[docs] Clean up some more llvm-gcc stuff

Some references to llvm-gcc were so crusty that I wasn't sure how to
proceed and so I've left them intact.

I also slipped in a quick peephole fix to use a :doc: link instead of
raw HTML link.

Avoid an infinite cycle with private linkage and -f{data|function}-sections.

When outputting an object we check its section to find its name, but when
looking for the section with -ffunction-section we look for the symbol name.

Break the loop by requesting a name with the private prefix when constructing
the section name. This matches the behavior before r201608.

Use PrivateLinkage now that it is safe.

Now that llvm's codegen knows to use an 'l' prefix when needed, we can just
use PrivateLinkage.

MCAsmParser: change representation of MCAsmMacroParameter

Rather than using std::pair, create a structure to represent the type.  This is
a preliminary refactoring to enable required parameter handling.  Additional
state is needed to indicate required parameters.  This has a minor side effect
of improving readability by providing more accurate names compared to first and
second.

MCAsmParser: support required parameters

This enhances the macro parser to parse and handle parameter qualifications,
which is needed to support required formal parameters in macro definitions.  A
required parameter may not be defaulted (though providing a default value is
accepted with a warning).  This improves GAS compatibility.

Partially addresses PR9248.

llvm-objdump/COFF: Print load configuration table.

Load Configuration Table may contain a pointer to SEH table. This patch is to
print the offset to the table. Printing SEH table contents is a TODO.

The layout of Layout Configuration Table is described in Microsoft PE/COFF
Object File Format Spec, but the table's offset/size descriptions seems to be
totally wrong, at least in revision 8.3 of the spec. I believe the table in
this patch is the correct one.
