Bradley Smith d27a6a7072 [ARM] Add DSP build attribute and extension targeting
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.

Xinliang David Li bc05e4e4c0 [Coverage] Add a test case for comdat
The binary contains two (merged) covmap sections which
have duplicate CovMapRecords from comdat (template instantation).
This test makes sure the reader reads it properly. It also
tests that the coverage data from different instantiations
of the same template function are properly merged in show
output.

Simon Atanasyan 2d0d8530e3 [llvm-readobj][ELF] Teach llvm-readobj to show arch specific ELF section's flags
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.

Sergei Larin d19d4d30d8 Add to the split module utility an SCC based method which allows not to globalize any local variables.
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).
    
    Joint development Tobias Edler von Koch (tobias@codeaurora.org) and Sergei Larin (slarin@codeaurora.org)

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.

Reid Kleckner 72e2ba7abb [readobj] Expand CodeView dumping functionality
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.

Kevin Enderby 0ae163f9ea For llvm-objdump, add the option -private-header (without the trailing ’s’)
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’).

Pete Cooper 6c97f4c7d7 Improve DWARFDebugFrame::parse to also handle __eh_frame.
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.

Nathan Slingerland 7f5b47ddd4 [llvm-profdata] Add support for weighted merge of profile data (2nd try)
Summary:
This change adds support for specifying a weight when merging profile data with the llvm-profdata tool.
Weights are specified by using the --weighted-input=<weight>,<filename> option. Input files not specified
with this option (normal positional list after options) are given a default weight of 1.

Adding support for arbitrary weighting of input profile data allows for relative importance to be placed on the
input data from multiple training runs.

Both sampled and instrumented profiles are supported.
