llvm-symbolizer will consult one of the .dSYM paths passed via -dsym-hint
if it fails to find the .dSYM bundle at the default location.

The plugin API doesn't have the notion of linkonce, only weak. It is up to the
plugin to figure out if a symbol used only for the symbol table can be dropped.
In particular, it has to avoid dropping a linkonce_odr selected by gold if there
is also a weak_odr.

The call to copyAttributesFrom will copy the visibility, which might assert
if it were to produce something invalid like "internal hidden". We avoid it
by first creating the replacement with the original linkage and then setting
it to internal affter the call to copyAttributesFrom.

When creating an internal function replacement for use in an alias we were
not remapping the argument uses in the instructions to point to the new
arguments.

Codeview line tables for functions in different sections refer to a common
STRING_TABLE_SUBSECTION for filenames.
This happens when building with -Gy or with inline functions with MSVC.

This patch defines a new iterator for the imported symbols.
Make a change to COFFDumper to use that iterator to print
out imported symbols and its ordinals.

When the flag is given, the command prints out the COFF import table.
Currently only the import table directory will be printed.
I'm going to make another patch to print out the imported symbols.
The implementation of import directory entry iterator in
COFFObjectFile.cpp was buggy. This patch fixes that too.

This commit adds a test which checks that the functions defined in header files will get associated with the header files rather than the source files in the reports.

So in fully linked images when a call is made through a stub it now gets a
comment like the following in the disassembly:
callq 0x100000f6c ## symbol stub for: _printf
indicating the call is to a symbol stub and which symbol it is for. This is
done for branch reference types and seeing if the branch target is in a stub
section and if so using the indirect symbol table entry for that stub and
using that symbol table entries symbol name.

If we have multiple coverage counts for the same segment, we need to
add them up rather than arbitrarily choosing one. This fixes that and
adds a test with template instantiations to exercise it.

get the literal string “Hello world” printed as a comment on the instruction
that loads the pointer to it. For now this is just for x86_64. So for object
files with relocation entries it produces things like:
leaq L_.str(%rip), %rax ## literal pool for: "Hello world\n"
and similar for fully linked images like executables:
leaq 0x4f(%rip), %rax ## literal pool for: "Hello world\n"
Also to allow testing against darwin’s otool(1), I hooked up the existing
-no-show-raw-insn option to the Mach-O parser code, added the new Mach-O
only -full-leading-addr option to match otool(1)'s printing of addresses and
also added the new -print-imm-hex option.

For biendian targets like ARM and AArch64, it is useful to have the
output of the llvm-dwarfdump and llvm-objdump report the endianness
used when the object files were generated.

This change fixes the ARM and AArch64 relocation visitors in
RelocVisitor. They were unconditionally assuming the object data are
little-endian. Tests have been added to ensure that the
llvm-dwarfdump utility does not crash when processing big-endian
object files.

potentially matching the check lines themselves.

This format is simply a regular object file with the bitcode stored in a
section named ".llvmbc", plus any number of other (non-allocated) sections.
One immediate use case for this is to accommodate compilation processes
which expect the object file to contain metadata in non-allocated sections,
such as the ".go_export" section used by some Go compilers [1], although I
imagine that in the future we could consider compiling parts of the module
(such as large non-inlinable functions) directly into the object file to
improve LTO efficiency.

First step done in this commit is to get flush out enough of the
SymbolizerGetOpInfo() routine to symbolic an X86_64 hello world .o and
its loading of the literal string and call to printf. Also the code to
symbolicate the X86_64_RELOC_SUBTRACTOR relocation and a test is also
added to show a slightly more complicated case.
Next will be to flush out enough of SymbolizerSymbolLookUp() to get the
literal string “Hello world” printed as a comment on the instruction that load
the pointer to it.
