* c-indentation.c (should_warn_for_misleading_indentation): When
suppressing warnings about cases where the guard and body are on
the same column, only use the first non-whitespace column in place
of the guard token column when dealing with "else" clauses.
When rejecting aligned BODY and NEXT, loosen the requirement
from equality with the first non-whitespace of guard to simply
that they not be indented relative to it.

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.
