All cores which add a cpu_addrcost_table use a non-zero value for
HI and TI mode shifts (a non-zero value for general indexing also
applies to all shifts). Given this, it makes no sense to use a
different setting in generic_addrcost_table. So change it so that
all supported cores, including -mcpu=generic, now generate the same:
int f(short *p, short *q, long x) { return p[x] + q[x]; }
lsl x2, x2, 1
ldrsh w3, [x0, x2]
ldrsh w0, [x1, x2]
add w0, w3, w0
ret

For the reasons explained in PR77536, niter_for_unrolled_loop assumes 5
iterations in the absence of profiling information, although it doesn't
increase beyond the estimate for the original loop. This left a hole in
which the new estimate could be less than the old one but still greater
than the limit imposed by CEIL (nb_iterations_upper_bound, unroll factor).

The GCC documentation in section 6.60.8 ARM Floating Point Status and
Control Intrinsics states that the FPSCR register can be read and
written to using the intrinsics __builtin_arm_get_fpscr and
__builtin_arm_set_fpscr. However, these are misnamed within GCC itself
and these intrinsic names are not recognised.
This patch corrects the intrinsic names to match the documentation, and
adds tests to verify these intrinsics generate the correct
instructions.

The existing fix-it printer can lead to difficult-to-read output
when fix-it hints are near each other. For example, in a recent
patch to add fix-it hints to the C++ frontend's -Wold-style-cast,
e.g. for:
foo *f = (foo *)ptr->field;
^~~~~
the fix-it hints:
replace the open paren with "const_cast<"
replace the close paren with "> ("
insert ")" after the "ptr->field"
would be printed in this odd-looking way:
foo *f = (foo *)ptr->field;
^~~~~
-
const_cast<
-
> ( )
class rich_location consolidates adjacent fix-it hints, which helps
somewhat, but the underlying problem is that the existing printer
simply walks through the list of hints printing them, starting newlines
as necessary.
This patch reimplements fix-it printing by introducing a planning
stage: a new class line_corrections "plans" how to print the
fix-it hints affecting a line, generating a vec of "correction"
instances. Hints that are sufficiently close to each other are
consolidated at this stage.
This leads to the much more reasonable output for the above case:
foo *f = (foo *)ptr->field;
^~~~~
-----------------
const_cast<foo *> (ptr->field);
where the 3 hints are consolidated into one "correction" at printing.
