If the user asks for a stack clash probe interval of 64kB, we currently
generate a "stdu rX,-65536(r1)" instruction.  That instruction does not
exist (the offset is a 16-bit signed number).  If the offset is too big
we should force it into a register and generate a "stdux rX,rY,r1"
instruction, instead.

A left shift of 1 can always be done using an add, so slightly adjust rtx
cost for DImode left shift by 1 so that adddi3 is preferred in all cases,
and the arm_ashldi3_1bit is redundant.

DImode right shifts of 1 are rarely used (6 in total in the GCC binary),
so there is little benefit of the arm_ashrdi3_1bit and arm_lshrdi3_1bit
patterns.  The generated code is better and faster without these shifts
as it allows early expansion, optimization and better register allocation.

C17, a bug-fix version of the C11 standard with DR resolutions
integrated, will soon go to ballot.  This patch adds corresponding
options -std=c17, -std=gnu17 (new default version, replacing
-std=gnu11 as the default), -std=iso9899:2017.  As a bug-fix version
of the standard, there is no need for flag_isoc17 or any options for
compatibility warnings; however, there is a new __STDC_VERSION__
value, so new cpplib languages CLK_GNUC17 and CLK_STDC17 are added to
support using that new value with the new options.  (If the standard
ends up being published in 2018 and being known as C18, option aliases
can be added.  Note however that -std=iso9899:199409 corresponds to a
__STDC_VERSION__ value rather than a publication date.)

(There are a couple of DR resolutions needing implementing in GCC, but
that's independent of the new options.)

(I'd propose to add -std=c2x / -std=gnu2x / -Wc11-c2x-compat for the
next major C standard revision once there are actually C2x drafts
being issued with new features included.)

Bootstrapped with no regressions for x86_64-pc-linux-gnu.
