We already perform it at the beginning of the function so we can't
arrive here with an invalid object. Also, add a test so that bugs
won't sneak in the future.

MCJIT emits zero-length CIE at the end of the _eh_frame section. This change
ensures that parser inside DebugInfo will not crash and correctly record such cases.
We are now recording DW_EH_PE_omit as a default value for FDE and LSDA encodings.
Also Offset != EndAugmentationOffset assertion check will only happen if augmentation
string had 'z' letter in it.

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.

Summary:
Currently llvm::SplitModule as the first step globalizes all local objects, which might not be desirable in some scenarios.
This change adds a new flag to llvm::SplitModule that uses SCC approach to search for a balanced partition without the need to externalize symbols.
Such partition might not be possible or fully balanced for a given number of partitions, and is a function of the module properties (global/local dependencies within the module).

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 adds a detailed profile summary in llvm-profdata. The summary is in the
form of one or more triples of the form (P, N, M) which is interpreted as if
we look at the Top-N counts in the profile, their sum accounts for P percentage
of the sum of all counts in the program and the minimum count in the Top-N is M.

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.

to only print the first private header.
Which for Mach-O files only prints the Mach header and not the subsequent load
commands. Which is used by scripts to match what the darwin otool(1) with the
-h flag does without the -l flag.
For non-Mach-O files it has the same functionality as -private-headers (with
the trailing ’s’).

many times so it is more efficient. Update unit test to remove

Summary:
There are a number of files in the tree which have been accidentally checked in with DOS line endings. Convert these to native line endings.
There are also a few files which have DOS line endings on purpose, and I have set the svn:eol-style property to 'CRLF' on those.

LLVM MC has single methods which can handle the output of EH frame and DWARF CIE's and FDE's.
This code improves DWARFDebugFrame::parse to do the same for parsing.
This also allows llvm-objdump to support the --dwarf=frames option which objdump supports. This
option dumps the .eh_frame section using the new code in DWARFDebugFrame::parse.

Third patch split out from http://reviews.llvm.org/D14752.
Only map in needed DISubroutine metadata (imported or otherwise linked

This is supported for ThinLTO, LTO and llvm-link --only-needed, with
associated tests for each one.
