Clang complains about an ambiguous call to printNumber() because it
can't work out what size_t should convert to. I picked uint64_t.

To better match the old darwin otool(1) behavior, when llvm-obdump(1) is used
with the -macho option and the input file is not an object file simply print
the file name and this message:
foo: is not an object file
and continue on to process other input files. Also in this case don’t exit
non-zero. This should help in some OSS projects' with autoconf scripts
that are expecting the old darwin otool(1) behavior.

We had various variants of defining dump() functions in LLVM. Normalize
them (this should just consistently implement the things discussed in
http://lists.llvm.org/pipermail/cfe-dev/2014-January/034323.html
For reference:
- Public headers should just declare the dump() method but not use
LLVM_DUMP_METHOD or #if !defined(NDEBUG) || defined(LLVM_ENABLE_DUMP)
- The definition of a dump method should look like this:
#if !defined(NDEBUG) || defined(LLVM_ENABLE_DUMP)
LLVM_DUMP_METHOD void MyClass::dump() {
// print stuff to dbgs()...
}
#endif

R_X86_64_NONE can be emitted without a symbol associated (well,
in theory it should never be emitted in an ABI-compliant relocatable
object). So, if there's no symbol associated to a reloc, emit one
with an empty name, instead of crashing.

This change introduces adjustPassManager target callback giving a
target an opportunity to tweak PassManagerBuilder before pass
managers are populated.
This generalizes and replaces addEarlyAsPossiblePasses target
callback. In particular that can be used to add custom passes to
extension points other than EP_EarlyAsPossible.

This allows MIR passes to emit optimization remarks with the same level
of functionality that is available to IR passes.
It also hooks up the greedy register allocator to report spills. This
allows for interesting use cases like increasing interleaving on a loop
until spilling of registers is observed.
I still need to experiment whether reporting every spill scales but this
demonstrates for now that the functionality works from llc
using -pass-remarks*=<pass>.

This is not a list of pairs, it is a hash table data structure. We now
correctly parse this out and dump it from llvm-pdbdump.
We still need to understand the conditions that lead to a type
getting an entry in the hash adjuster table. That will be done
in a followup investigation / patch.

Summary:
Add a new load command LC_BUILD_VERSION. It is a generic version of
LC_*_VERSION_MIN load_command used on Apple platforms. Instead of having
a seperate load command for each platform, LC_BUILD_VERSION is recording
platform info as an enum. It also records SDK version, min_os, and tools
that used to build the binary.

This is a stub implementation of the `-s` or `--format` option that
allows the user to specify the demangling style. Since we only support
the Itanium (GNU) style demangling, auto is synonymous with `gnu`.
Simply swallow the option to permit some level of commandline
compatibility.

While the builder pattern has proven useful for certain other
larger types, in this case it was hampering the ability to use
the data structure, as for runtime access we need a map that
we can efficiently read from and write to. So the two are merged
into a single data structure that can efficiently be read to,
written from, deserialized from bytes, and serialized to bytes.

By default c++filt demangles functions, though you can optionally pass
`-t` to have it decode types as well, behaving nearly identical to
`__cxa_demangle`. Add support for this mode.

c++filt does not attempt to demangle symbols which do not match its
expected format. This means that the symbol must start with _Z or ___Z
(block invocation function extension). Any other symbols are returned
as is. Note that this is different from the behaviour of __cxa_demangle
which will demangle fragments.

Removed all DWARFDie::getAttributeValueAs*() calls.
Renamed:
Optional<DWARFFormValue> DWARFDie::getAttributeValue(dwarf::Attribute);
To:
Optional<DWARFFormValue> DWARFDie::find(dwarf::Attribute);
Added:
Optional<DWARFFormValue> DWARFDie::findRecursively(dwarf::Attribute);
All decoding of Optional<DWARFFormValue> values are now done using the dwarf::to*() functions from DWARFFormValue.h:
Old code:
auto DeclLine = DWARFDie.getAttributeValueAsSignedConstant(DW_AT_decl_line).getValueOr(0);
New code:
auto DeclLine = toUnsigned(DWARFDie.find(DW_AT_decl_line), 0);
This composition helps us since we can now easily do:
auto DeclLine = toUnsigned(DWARFDie.findRecursively(DW_AT_decl_line), 0);
This allows us to easily find attribute values in the current DIE only (the first new code above) or in any DW_AT_abstract_origin or DW_AT_specification Dies using the line above. Note that the code line length is shorter and more concise.

Revert [ARM] Fix ubig32_t read in ARMAttributeParser
Now using support functions to read data instead of trying to
perform casts.
===========================================================
Revert [ARM] Enable objdump to construct triple for ARM
Now that The ARMAttributeParser has been moved into the library,
it has been modified so that it can parse the attributes without
printing them and stores them in a map. ELFObjectFile now queries
the attributes to fill out the architecture details of a provided
triple for 'arm' and 'thumb' targets. llvm-objdump uses this new
functionality.
