llvmorg-10.0.1-rc2-0-g77d76b71d7d.

Also add a few more llvm utilities under WITH_CLANG_EXTRAS:

* llvm-dwp, a utility for merging DWARF 5 Split DWARF .dwo files into
  .dwp (DWARF package files)
* llvm-size, a size(1) replacement
* llvm-strings, a strings(1) replacement

.SH SYNOPSIS
.sp
\fBllvm\-size\fP [\fIoptions\fP] [\fIinput...\fP]
.SH DESCRIPTION
.sp
\fBllvm\-size\fP is a tool that prints size information for binary files.
It is intended to be a drop\-in replacement for GNU\(aqs \fBsize\fP\&.
.sp
The tool prints size information for each \fBinput\fP specified. If no input is
specified, the program prints size information for \fBa.out\fP\&. If "\fB\-\fP" is
specified as an input file, \fBllvm\-size\fP reads a file from the standard
input stream. If an input is an archive, size information will be displayed for
all its members.
.SH OPTIONS
.INDENT 0.0
.TP
.B \-A
Equivalent to \fI\%\-\-format\fP with a value of \fBsysv\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-arch=<arch>
Architecture(s) from Mach\-O universal binaries to display information for.
.UNINDENT
.INDENT 0.0
.TP
.B \-B
Equivalent to \fI\%\-\-format\fP with a value of \fBberkeley\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-common
Include ELF common symbol sizes in bss size for \fBberkeley\fP output format, or
as a separate section entry for \fBsysv\fP output. If not specified, these
symbols are ignored.
.UNINDENT
.INDENT 0.0
.TP
.B \-d
Equivalent to \fI\%\-\-radix\fP with a value of \fB10\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B \-l
Display verbose address and offset information for segments and sections in
Mach\-O files in \fBdarwin\fP format.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-format=<format>
Set the output format to the \fB<format>\fP specified. Available \fB<format>\fP
options are \fBberkeley\fP (the default), \fBsysv\fP and \fBdarwin\fP\&.
.sp
Berkeley output summarises text, data and bss sizes in each file, as shown
below for a typical pair of ELF files:
.INDENT 7.0
.INDENT 3.5
.sp
.nf
.ft C
$ llvm\-size \-\-format=berkeley test.o test2.o

182 16 5 203 cb test.elf
82 8 1 91 5b test2.o
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
For Mach\-O files, the output format is slightly different:
.INDENT 7.0
.INDENT 3.5
.sp
.nf
.ft C
$ llvm\-size \-\-format=berkeley macho.obj macho2.obj
__TEXT __DATA __OBJC others dec hex

16 32 0 0 48 30 macho2.obj
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
Sysv output displays size and address information for most sections, with each
file being listed separately:
.INDENT 7.0
.INDENT 3.5
.sp
.nf
.ft C
$ llvm\-size \-\-format=sysv test.elf test2.o
test.elf :
section size addr
.eh_frame 92 2097496
.text 90 2101248

Total 199
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
\fBdarwin\fP format only affects Mach\-O input files. If an input of a different
file format is specified, \fBllvm\-size\fP falls back to \fBberkeley\fP
format. When producing \fBdarwin\fP format, the tool displays information about
segments and sections:
.INDENT 7.0
.INDENT 3.5
.sp
.nf
.ft C
$ llvm\-size \-\-format=darwin macho.obj macho2.obj
macho.obj:
Segment : 12

\fBllvm\-strings\fP [\fIoptions\fP] [\fIinput...\fP]
.SH DESCRIPTION
.sp
\fBllvm\-strings\fP is a tool intended as a drop\-in replacement for GNU\(aqs
\fBstrings\fP, which looks for printable strings in files and writes them
to the standard output stream. A printable string is any sequence of four (by
default) or more printable ASCII characters. The end of the file, or any other
byte, terminates the current sequence.
.sp
\fBllvm\-strings\fP looks for strings in each \fBinput\fP file specified.
Unlike GNU \fBstrings\fP it looks in the entire input file, regardless of
file format, rather than restricting the search to certain sections of object
files. If "\fB\-\fP" is specified as an \fBinput\fP, or no \fBinput\fP is specified,
the program reads from the standard input stream.
