Fix a silly copy-paste error in the tool description. Take the
opportunity to add crash stack printing which will hopefully never be
needed.

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.

It describes a region of arbitrary data included in a Mach-O file.
Its initial use is to record extra data in MH_CORE files.

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.

Enable an ELFObjectFile to read the its arm build attributes to
produce a target triple with a specific ARM architecture.
llvm-objdump now uses this functionality to automatically produce
a more accurate target.

Here we define the `graph` subcommand which generates a graph from the function
call information and uses it to present the call information graphically with
additional annotations.

std::to_string is not available in the android ndk. Using llvm::to_string
instead.
Committing as obvious.

This is uncovered when running tools/dsymutil/X86/empty_range.s.test
with ASAN. Haven't investigate yet, whether that means there is an ODR
violation in that test.

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.

Summary:
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.
