e29132d427 [Mips] Fix handling of R_MIPS_GOT16 relocation and building local part 
of GOT.
 * Read addend for R_MIPS_GOT16 relocation.
 * Put only high 16 bits of symbol + addend into GOT entries for
   locally visible symbols.

7ad72ebc5e [PECOFF] Support yet another new type of weak symbol. 
COMDAT_SELECT_LARGEST is a COMDAT type that make linker to choose the largest
definition from among all of the definition of a symbol. If the size is the
same, the choice is arbitrary.

a7236598bb [PECOFF] Data type of SectionNumber is now unsigned (r203986). 
So we don't need static_cast's to convert it from signed to unsigned.

74af50134b [PECOFF] Handle large objects having more than 32768 sections. 
The COFF spec says that the SectionNumber field in the symbol table is 16 bit
signed type, but MSVC treats the field as if it is unsigned.

13c70b6d4b Replace OwningPtr with std::unique_ptr. 
This results in some simplifications to the code where an OwningPtr had to
be used with the previous api and then ownership moved to a unique_ptr for
the rest of lld.

c83b4eb3a1 [PECOFF] Handle objects with unknown machine type header value. 
An object whose machine type header value is unknown looks a bit odd but
is valid. If an object contains only machine-type-independent data, you
can leave the type field unspecified. Some files in oldname.lib are such
object files.

c79dd2f80a [PECOFF] Support a new type of weak symbol. 
Summary:
COMDAT_SELECT_SAME_SIZE is a COMDAT type that I presume exist only in COFF.
The semantics of the type is that linker should merge such COMDAT sections if
their sizes are the same. Otherwise it's an error.

182437e63f [PECOFF] Sort x64 exception handler table. 
Just like x86 exception handler table, the table for x64 needs to be sorted
so that runtime can binary search on it. Unlike x86, the table entry for x64
has multiple fields, and they need to be sorted according to its BeginAddress
field. This patch also fixes a bug in relocations.
