SHT_GNU_verneed (.gnu.version_r) is a version dependency section.
It was the last symbol versioning relative section that was not dumped,
now it is.

This directory is used to find if there is a PDB associated with an
executable. I plan to use this functionality to teach llvm-symbolizer
whether it should use DIA or DWARF to symbolize a given DLL.

Main problem here was that SHF_COMPRESSED has the same value with
XCORE_SHF_CP_SECTION, which was included as standart (common) flag.
As far I understand xCore is a family of controllers and it that
means it's constant should be processed separately,
only if e_machine == EM_XCORE, otherwise llvm-readobj would output
different constants twice for compressed section:
Flags [
..
SHF_COMPRESSED (0x800)
..
XCORE_SHF_CP_SECTION (0x800)
..
]
what probably does not make sence if you're not working with xcore file.

This just checks that we emit all type records once, and then after
merging the type stream with no other type streams, we still emit every
kind of type record.
We could test the dumper output more closely, but that would make the
test very brittle. Currently we're just getting coverage.
llvm-svn: 269778
Summary:
This code is intended to be used as part of LLD's PDB writing. Until
that exists, this is exposed via llvm-readobj for testing purposes.
Type stream merging uses the following algorithm:
- Begin with a new empty stream, and a new empty hash table that maps
from type record contents to new type index.
- For each new type stream, maintain a map from source type index to
destination type index.
- For each record, copy it and rewrite its type indices to be valid in
the destination type stream.
- If the new type record is not already present in the destination
stream hash table, append it to the destination type stream, assign it
the next type index, and update the two hash tables.
- If the type record already exists in the destination stream, discard
it and update the type index map to forward the source type index to
the existing destination type index.

.MIPS.options section specifies miscellaneous options to be applied
to an object file. LLVM as well as modern versions of GNU tools emit
the only type of the options - ODK_REGINFO. The patch teaches llvm-readobj
to print details of the ODK_REGINFO and skip contents of other options.

The patch supports common STV_xxx visibility flags and MIPS specific
STO_MIPS_xxx flags.

This adds support for finding the dynamic table and dynamic symbol table via
the section table or the program header table. If there's no section table an
attempt is made to figure out the length of the dynamic symbol table.

It is possible to have .got section and one or more zero-sized section
at the same address. This patch first checks that GOT (or GOT PLT)
section should have non-zero size using corresponding dynamic tags. Then
it looks up not empty section at the specified address.

This patch was originally committed as r257885, but was reverted due to windows
failures. The cause of these failures has been fixed under r258677, hence
re-committing the original patch.

Some architecture specific ELF section flags might have the same value
(for example SHF_X86_64_LARGE and SHF_HEX_GPREL) and we have to check
machine architectures to select an appropriate set of possible flags.
The patch selects architecture specific flags into separate arrays
`ElfxxxSectionFlags` and combines `ElfSectionFlags` and `ElfxxxSectionFlags`
before pass to the `StreamWriter::printFlags()` method.

Added forgotten ELFDumper.cpp to commit.
Initial commit message:
[llvm-readobj] Add support for TLSDESC_PLT and TLSDESC_GOT dynamic section tags to the llvm-readobj.
If module uses uses lazy TLSDESC relocations it should define DT_TLSDESC_PLT and DT_TLSDESC_GOT entries.
They were unknown for llvm-readobj before this patch.

This rewrites and expands the existing codeview dumping functionality in
llvm-readobj using techniques similar to those in lib/Object. This defines a
number of new records and enums useful for reading memory mapped codeview
sections in COFF objects.
The dumper is intended as a testing tool for LLVM as it grows more codeview
output capabilities.
