IBM Z: Spectre: Prevent thunk cfi to be emitted with -fno-dwarf2-cfi-asm
The CFI magic we emit as part of the indirect branch thunks in order to
have somewhat sane unwind information must not be emitted with
-fno-dwarf2-cfi-asm.

[ARM][PR target/84826] Fix ICE in extract_insn, at recog.c:2304 on
arm-linux-gnueabihf
This patch backports r258777 and r258805 to gcc-7-branch
and gcc-6-branch. The same ICE occurs in both the branches with
-fstack-check. Thus the test case directive has been changed.
The discussion on the patch that went into trunk is:

This adds a new option -mreadonly-in-sdata (on by default) that
controls whether readonly data can be put in sdata. (For EABI this
does nothing, readonly data is put in sdata2 as usual).
