Expand the gtm_jmpbuf structure by one word field to add
Intel CET support further. The code in sjlj.S already
allocates more space on the stack then gtm_jmpbuf needs.
Use this extra space to absorb the new field.
The structure is allocated on the stack in such a way
that eip/rsp field is overlapped with return address on
the stack. Locate the new field right before eip/rsp so
code that accesses buffer fields relative to address of
gtm_jmpbuf has its offsets unchanged.
* libitm/config/x86/target.h: Add new field (ssp).
* libitm/config/x86/sjlj.S: Change offsets.

Since GTM::gtm_thread has

The attached patch adds the a target specific attribute via the
new target macro TARGET_BEGIN_TRANSACTION_ATTRIBUTE to the
function begin_transaction(). S/390 uses this to set the
soft-float target attribute which is needed to fix a crash with
-m31.
As there seems to be no place in libitm to document internal macros like
USE_HTM_FASTPATH or the new macro, I've put the documentation in a
comment where the macro is used.

* config/s390/target.h (TARGET_BEGIN_TRANSACTION_ATTRIBUTE): Define
function attribute to disable floating point in begin_transaction() on

This patch adds an easy way to write tests for expected multiline
output. For example we can test carets and underlines for
a particular diagnostic with:
/* { dg-begin-multiline-output "" }
typedef struct _GMutex GMutex;
^~~~~~~
{ dg-end-multiline-output "" } */
multiline.exp is used by prune.exp; hence we need to load it before
prune.exp via *load_gcc_lib* for the testsuites of the various
non-"gcc" support libraries (e.g. boehm-gc).
gcc/testsuite/ChangeLog:
* lib/multiline.exp: New file.
* lib/prune.exp: Load multiline.exp.
(prune_gcc_output): Call into multiline.exp to handle any
multiline output directives.

load_gcc_lib.
