aarch64 - Set the mode for the unspec in speculation_tracker insn.
The speculation tracker insn in my recent patch set for CVE-2017-5753
was missing a mode on the UNSPEC. Although this didn't break the
build, it did cause an unnecessary warning from the MD parsing
mechanism that I missed at the time. It's a trivial fix, as follows:
* config/aarch64/aarch64.md (speculation_tracker): Set the mode for
the UNSPEC.
In order to properly fix PR87762, we need to distinguish between
instructions which support relative addressing and instructions which
don't. We could check whether the existing "type" attribute is equal to
"larl", but there are notable exceptions (lrl, for example), and
changing them makes scheduling worse on z10. We could also check
whether the existing "op_type" attribute is equal to "RIL-b" or "RIL-c".
However, adding a new attribute provides more flexibility, since we
don't depend idiosyncrasies which might be introduced into PoP in the
future.

Update most of libquadmath/math/ from glibc, automate update (PR libquadmath/68686).
libquadmath sources are mostly based on glibc sources at present, but
derived from them by a manual editing / substitution process and with
subsequent manual merges. The manual effort involved in merges means
they are sometimes incomplete and long-delayed.
Since libquadmath was first created, glibc's support for this format
has undergone significant changes so that it can also be used in glibc
to provide *f128 functions for the _Float128 type from TS 18661-3.
This makes it significantly easier to use it for libquadmath in a more
automated fashion, since glibc has a float128_private.h header that
redefines many identifiers as macros as needed for building *f128
functions.
Simply using float128_private.h directly in libquadmath, with
unmodified glibc sources except for changing function names in that
one header to be *q instead of *f128, would be tricky, given its
dependence on lots of other glibc-internal headers (whereas
libquadmath supports non-glibc systems), and also given how some libm
functions in glibc are built from type-generic templates using a
further set of macros rather than from separate function
implementations for each type.
So instead this patch adds a script update-quadmath.py to convert
glibc sources into libquadmath ones, and the script reads
float128_private.h to identify many of the substitutions it should
make. quadmath-imp.h is updated with various new internal
definitions, taken from glibc as needed; this is the main place
expected to need updating manually when subsequent merges from glibc
are done using the script. No attempt is made to make the script
output match the details of existing formatting, although the
differences are of a size that makes a rough comparison (ignoring
whitespace) possible.
Two new public interfaces are added to libquadmath, exp2q and
issignalingq, at a new QUADMATH_1.2 symbol version, since those
interfaces are used internally by some of the glibc sources being
merged into libquadmath; although there is a new symbol version, no
change however is made to the libtool version in the libtool-version
file. Although there are various other interfaces now in glibc libm
but not in libquadmath, this patch does nothing to add such interfaces
(although adding many of them would in fact be easy to do, given the
script).
One internal file (not providing any public interfaces),
math/isinf_nsq.c, is removed, as no longer used by anything in
libquadmath after the merge.
Conditionals in individual source files on <fenv.h> availability or
features are moved into quadmath-imp.h (providing trivial macro
versions of the functions if real implementations aren't available),
to simplify the substitutions in individual source files. Note
however that I haven't tested for any configurations lacking <fenv.h>,
so further changes could well be needed there.
Two files in libquadmath/math/ are based on glibc sources but not
updated in this patch: fmaq.c and rem_pio2q.c. Both could be updated
after further changes to the script (and quadmath-imp.h as needed); in
the case of rem_pio2q.c, based on two separate glibc source files,
those separate files would naturally be split out into separate
libquadmath source files in the process (as done in this patch with
expq_table.h and tanq_kernel.c, where previously two glibc source
files had been merged into one libquadmath source file). complex.c,
nanq.c and sqrtq.c are not based on glibc sources (though four of the
(trivial) functions in complex.c could readily be replaced by instead
using the four corresponding files from glibc, if desired).
libquadmath also has printf/ and strtod/ sources based on glibc, also
mostly not updated for a long time. Again the script could no doubt
be made to generate those automatically, although that would be a
larger change (effectively some completely separate logic in the
script, not sharing much if anything with the existing code).
Bootstrapped with no regressions on x86_64-pc-linux-gnu.

Avoid stray [] in ia64 assembler test.
Noted in <https://gcc.gnu.org/ml/gcc-patches/2018-11/msg00034.html>.
Fix by adding extra newline in test input is analogous to many such
newlines added in cases where argument to a newly added AC_LANG_SOURCE
had a preprocessor directive on its last line.
