GDB 8.1.1 brings the following fixes and enhancements over GDB 8.1:

 * PR gdb/22824 (misleading description of new rbreak Python function in GDB 8.1 NEWS file)
 * PR gdb/22849 (ctrl-c doesn't work in extended-remote)
 * PR gdb/22907 ([Regression] gdbserver doesn't work with filename-only binaries)
 * PR gdb/23028 (inconsistent disassemble of vcvtpd2dq)
 * PR gdb/23053 (Fix -D_GLIBCXX_DEBUG gdb-add-index regression)
 * PR gdb/23127 ([AArch64] GDB cannot be used for debugging software that uses high Virtual Addresses)

 * PR breakpoints/23210 ([8.1/8.2 Regression] Bogus Breakpoint address adjusted from 0xf7fe7dd3 to 0xfffffffff7fe7dd3)

GDB 8.1 includes the following changes and enhancements:

  * Breakpoints on C++ functions are now set on all scopes by default
    ("wild" matching);

  * Support for inserting breakpoints on functions marked with C++ ABI tags;

  * Target floating-point arithmetic emulation during expression evaluation
    (requires MPFR 3.1 or later);

  * Various Python Scripting enhancements;

  * Improved Rust support; in particular, Trait objects can now be inspected
    when debugging Rust code;

  * GDB no longer makes assumptions about the type of symbols without
    debugging information to avoid producing erroneous and often confusing
    results;

  * The 'enable' and 'disable' commands now accept a range of breakpoint
    locations;

  * New 'starti' command to start the program at the first instruction;

  * New 'rbreak' command to insert a number of breakpoints via a regular
    expression pattern (requires Python);

  * The 'ptype' command now supports printing the offset and size of
    the fields in a struct;

  * The 'gcore' command now supports dumping all the memory mappings
    ('-a' command-line option);

  * New shortcuts for TUI Single-Key mode: 'i' for stepi, and 'o' for nexti;

  * GDBserver enhancements:
    ** Support for transmitting environment variables to GDBserver;
    ** Support for starting inferior processes with a specified initial
       working directory;
    ** On Unix systems, support for globbing expansion and variable
       substitution of inferior command-line arguments;

  * Various completion enhancements;

  * The command used to compile and inject code with the 'compile' command
    is now configurable;

  * New '--readnever' command-line option to speed the GDB startup when
    debugging information is not needed;

  * Support for the following new native configurations:
    ** FreeBSD/aarch64 (aarch64*-*-freebsd*);
    ** FreeBSD/arm (arm*-*-freebsd*);

  * Support for the following new targets:
    ** FreeBSD/aarch64 (aarch64*-*-freebsd*);

Changes compared to GCC 7.x

001-revert_register_mode_search.patch dropped

The underlying issue is described at the end of
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58139

It is fixed by the upstream commit:
https://github.com/gcc-mirror/gcc/commit/3fa2798aa887d141d86985240f03e2f3809e7e62

020-PR-libstdc-81797-Add-.NOTPARALLEL-to-include-Makefil.patch dropped due to already upstream

100-PR-rtl-optimization-83496.patch dropped due to already upstream

910-mbsd_multi.patch
modified to fix ambiguous overloaded inform() call error

gcc/input.h
header: define UNKNOWN_LOCATION ((source_location) 0)

-        inform (0, "someone does not honour COPTS correctly, passed %d times",
-         honour_copts);
+        inform (UNKNOWN_LOCATION, "someone does not honour COPTS correctly, passed %d times",
+         honour_copts);

940-no-clobber-stamp-bits.patch dropped due to fixed upstream by another way
upstream commit: https://github.com/gcc-mirror/gcc/commit/87b2d547f8ac9778d66909b8726fe967d1efbc74

950-cpp_file_path_translation.patch dropped, Both -fmacro-prefix-map and -ffile-prefix-map are added
to gcc 8.1.0, if I understand it correctly, we should use -fmacro-prefix-map
usage: -fmacro-prefix-map=@var{old}=@var{new}
upstream commit: https://github.com/gcc-mirror/gcc/commit/859b51f83662d01e4f158ea9327db9ca37fe70b3

-iremap exists as a flag for a long time, for backward compatibility, I think we should keep the
variable name unchanged but change its value in rules.mk for gcc 8.x and higher.

Compile and run tested on x86_64
