Emit DW_TAG_type_units into the debug_info section using compile unit
headers. This is bogus/unusable by debuggers, but testable and provides
more isolated review.

Subsequent patches will include support for type unit headers and
emission into the debug_types section, as well as comdat grouping the
types based on their hash. Also the CompileUnit type will be renamed
'Unit' and relevant portions pulled out into respective CompileUnit and
TypeUnit types.

We are slicing an array of Value pointers and process those slices in a loop.
The problem is that we might invalidate a later slice by vectorizing a former
slice.

Use a WeakVH to track the pointer. If the pointer is deleted or RAUW'ed we can
tell.

The test case will only fail when running with libgmalloc.

Microsoft adds an extra byte of padding before laying out zero sized

This patch adds the same behavior to clang.

Instead of processing relocation for branch to stubs right away, emit a
modified relocation and add it to queue to be resolved later when final load
address is known.
This resolves seven MIPS MCJIT issues that were caused by missing relocation
fixups at the end.

The object files we support use null terminated strings, so there is no way to
support these.

This patch adds an assert to catch bad API use and an error check in the .ll

The previous patches tried to deduce the correct function type. I now realize
this is not possible in general. Consider

class foo {
    template <typename T> static void bar(T v);
};
extern template void foo::bar(const void *);

We will only know that bar is static after a lookup, so we have to handle this
in the template instantiation code.

This patch reverts my previous two changes (but not the tests) and instead
handles the issue in DeduceTemplateArguments.

This is the first step to fix pr17918.

It extends the .section directive a bit, inspired by what the ELF one looks
like. The problem with using linkonce is that given

.section foo
.linkonce....

.section foo
.linkonce

we would already have switched sections when getting to .linkonce. The cleanest
solution seems to be to add the comdat information in the .section itself.

Hard float for mips16 means essentially to compile as soft float but to
use a runtime library for soft float that is written with native mips32
