This patch adds the remainder of the main documentation changes.  It
adds the changes for -mcpu, -mtune and -mfpu.  I've chosen to document
the extension options under -mcpu rather than under -mtune because,
while they are permitted with -mtune, they do not affect the behaviour
of the tuning done by the compiler.

I've also inverted the sense of the table (making the primary index
the extension name and then listing the CPU names to which it applies.
This is because the extensions are much more orthoganal in meaning
here and having a primary entry via the CPU name would lead to
enormous duplication.

Finally, it adds the relevant changes to -mfpu.  I haven't stated yet
that any setting of -mfpu other than 'auto' is deprecated, but that is
certainly the long-term goal of this patch series.

	* doc/invoke.texi (ARM Options, -mcpu): Document supported
	extension options.
	(ARM Options, -mtune): Document that this accepts the same
	extension options as -mcpu.
	(ARM Options, -mfpu): Document addition of -mfpu=auto.

This adds documentation for the new extension options to -march= on ARM.
I tried a number of different ways of formatting the information, but this
seems the best, given what can be achieved in texinfo format.

	* doc/invoke.texi (ARM Options, -march=): Document new syntax and
	permitted extensions.

The MULTILIB_REUSE mapping rules are built up using periods to
represent the placement of '=' signs in the command line syntax.  This
presents a problem if the option contains an explicit period because
that is translated unconditionally.  The result is that it is not
currently possible to write a reuse rule that would match the
ARMv8-M mainline architecture:

	-march=armv8-m.main

To fix this, this patch allows an explicit period to be escaped by writing
\. and by then preserving the period into the generated multilib header.

	* genmultilib (multilib_reuse): Allow an explicit period to be escaped
	with a backslash.  Remove the backslash after substituting unescaped
	periods.
	* doc/fragments.texi (MULTILIB_REUSE): Document it.

Sometimes it is useful to generate pre-processed output to a file and
the dependency information to stdout for further analysis/processing.
For example:

g++ -E -MD -fdirectives-only -o test.ii test.cxx

This will generate the dependency information to test.d (as per the
documentation). While changing this behavior is probably unwise, one
traditional (e.g., supported by -o) way to handle this is to recognize
the special '-' file name as an instruction to write to stdout:

g++ -E -MD -fdirectives-only -o test.ii -MF - test.cxx

Currently this will create a file named '-'. The included patch
changes this behavior to write to stdout.

Note also that Clang has supported this from at least version 3.5.

-mno-gen-cell-microcode is a pain to handle correctly: it causes
different code generation for some very basic patterns, even patterns
specific to that option.  It also requires marking up many patterns,
which is a pain when adding new patterns or modifying existing ones
(first non-trivial step is finding the Cell BE manual!)

-mwarn-cell-microcode is very expensive, even more so after my recent
fix for PR43763; and it used to ICE for seven years before that fix.

This patch removes both these command line options (it leaves the
positive form of -mgen-cell-microcode, doing nothing, for
compatibility).

Where cc_reg_not_micro_cr0_operand was used, we now get the regular
cc_reg_not_cr0_operand.

One testcase used -mgen-cell-microcode and one its negation; both
are adjusted.
