From-SVN: r265494

The move constructor for the SSO string uses assign(const basic_string&)
when either:

(1) the source string is "local" and so the contents of the small string
buffer need to be copied, or

(2) the allocator does not propagate and is_always_equal is false.

Case (1) is suboptimal, because the assign member is not noexcept and
the compiler isn't smart enough to see it won't actually throw in this
case. This causes extra code in the move assignment operator so that any
exception will be turned into a call to std::terminate. This can be
fixed by copying small strings inline instead of calling assign.

Case (2) is a bug, because the specific instances of the allocators
could be equal even if is_always_equal is false. This can result in an
unnecessary deep copy (and potentially-throwing allocation) when the
storage should be moved. This can be fixed by simply checking if the
allocators are equal.

	* include/bits/basic_string.h [_GLIBCXX_USE_CXX11_ABI]
	(basic_string::operator=(basic_string&&)): For short strings copy the

Consider the following RTL:

(insn (set (mem/f/c:DI (reg/f:DI 60))
           (const:DI (plus:DI (symbol_ref:DI ("*.LANCHOR0"))
                              (const_int 8)))))

generated by cse2 pass.  It is matched to movdi_64, resulting in
the following inefficient code:

	larl	%r5,.L6			# Load literal pool@
	lg	%r1,.L7-.L6(%r5)	# Load .LANCHOR0+8
	stgrl	%r1,.LANCHOR0
	br	%r14

Matching it to movdi_larl improves the code, eliminating one
instruction and the literal pool entry:

	larl	%r1,.LANCHOR0+8
	stgrl	%r1,.LANCHOR0
	br	%r14

Taking it one step further, there is no reason to keep movdi_64 and
movdi_larl separate, since this could potentially improve code in other
ways by giving lra one more alternative to choose from.

r264556 and r264537 changed the format of EQ_ATTR_ALT RTXs to "ww",
which also required adjusting rtx_code_size initializer.  In order to
simplify things, the list of rtx_codes known to use HOST_WIDE_INTs was
replaced by the format string check.  However, unlike the old one, this
new check cannot be always performed at compile time, in which case a
static constructor is generated.  This may lead to a static
initialization order fiasco with respect to other static constructors
in the compiler, in case of PR87747, cselib's pool_allocator.

Currently, dg-cmp-results will not print anything for a test that was
not run before, even if it is a FAIL or UNRESOLVED now. This means that
when contributing a code change together with a testcase in the same
commit one must run dg-cmp-results twice: once to check for regression
on a full testsuite run and once against the new testcase with -v -v.
This also prevents using dg-cmp-results on sum files generated with
test_summary since these would not contain PASS.

This patch changes dg-cmp-results to print NA->FAIL and NA->UNRESOLVED
changes by default.

gcc.dg/sibcall-9.c and gcc.dg/sibcall-10.c give execution failure
on ARM when compiled with -fPIC due to the PIC access to volatile
variable v creating an extra spill which causes the frame size of the
two recursive functions to be different. Making the variable static
solve the issue because the variable can be access in a PC-relative way
and avoid the spill, while still testing sibling call as originally
intended.

The isolate-paths pass is activated by various -f flags, but also by
-Wnull-dereference.  Most of its codegen changes are conditioned on at
least one of the -f flags, but those that detect, warn about and
isolate paths that return the address of local variables are enabled
even if the pass is activated only by -Wnull-dereference.

-W flags should not cause codegen changes, so this patch makes the
codegen changes conditional on the presence of any of the -f flags
that activate the pass.  Should we have a separate option to activate
only this kind of transformation?
