Diff to previous 1.1.1.3 (colored)

initial import of GCC 9.3.0.  changes include:

- live patching support
- shell completion help
- generally better diagnostic output (less verbose/more useful)
- diagnostics and optimisation choices can be emitted in json
- asan memory usage reduction
- many general, and specific to switch, inter-procedure,
  profile and link-time optimisations.  from the release notes:
  "Overall compile time of Firefox 66 and LibreOffice 6.2.3 on
  an 8-core machine was reduced by about 5% compared to GCC 8.3"
- OpenMP 5.0 support
- better spell-guesser
- partial experimental support for c2x and c++2a
- c++17 is no longer experimental
- arm AAPCS GCC 6-8 structure passing bug fixed, may cause

import GCC 5.3.0.  see these urls for details which are too large to
include here:

	http://gcc.gnu.org/gcc-4.9/changes.html
	http://gcc.gnu.org/gcc-5/changes.html

(note that GCC 5.x is a release stream like GCC 4.9.x, 4.8.x, etc.)


the main issues we will have are:

The default mode for C is now -std=gnu11 instead of -std=gnu89.

ARM:
The deprecated option -mwords-little-endian has been removed.
The options -mapcs, -mapcs-frame, -mtpcs-frame and -mtpcs-leaf-frame
 which are only applicable to the old ABI have been deprecated.

MIPS:
The o32 ABI has been modified and extended. The o32 64-bit
 floating-point register support is now obsolete and has been removed.
 It has been replaced by three ABI extensions FPXX, FP64A, and FP64.
 The meaning of the -mfp64 command-line option has changed. It is now
 used to enable the FP64A and FP64 ABI extensions.
