341d0f4b9e llvm-objdump: Do not attempt to disassemble symbols outside of section
boundaries.

It is possible to create an ELF executable where symbol from say .text
section 'points' to the address outside the section boundaries. It does
not have a sense to disassemble something outside the section.

Without this fix llvm-objdump prints finite or infinite (depends on
the executable file architecture) number of 'invalid instruction
encoding' warnings.

b7e1ab7959 llvm-objdump/COFF: Print load configuration table.
Load Configuration Table may contain a pointer to SEH table. This patch is to
print the offset to the table. Printing SEH table contents is a TODO.

The layout of Layout Configuration Table is described in Microsoft PE/COFF
Object File Format Spec, but the table's offset/size descriptions seems to be
totally wrong, at least in revision 8.3 of the spec. I believe the table in
this patch is the correct one.

fb432acff8 llmv-objdump/COFF: Print export table contents.
This patch adds the capability to dump export table contents. An example
output is this:

  Export Table:
   Ordinal      RVA  Name
         5   0x2008  exportfn1
         6   0x2010  exportfn2

By adding this feature to llvm-objdump, we will be able to use it to check
export table contents in LLD's tests. Currently we are doing binary
comparison in the tests, which is fragile and not readable to humans.

This reverts commit r191472 because it's failing on BE machine.

0c873adc82 llvm-objdump: Dump COFF import table if -private-headers option is given.
This is a patch to add capability to llvm-objdump to dump COFF Import Table
entries, so that we can write tests for LLD checking Import Table contents.

llvm-objdump did not print anything but just file name if the format is COFF
and -private-headers option is given. This is a patch adds capability for
dumping DLL Import Table, which is specific to the COFF format.

In this patch I defined a new iterator to iterate over import table entries.
Also added a few functions to COFFObjectFile.cpp to access fields of the entry.
