gcc: Remove trailing whitespace

I've tried to build stage3 with
-Wleading-whitespace=blanks -Wtrailing-whitespace=blank -Wno-error=leading-whitespace=blanks -Wno-error=trailing-whitespace=blank
added to STRICT_WARN and that expectably resulted in about
2744 unique trailing whitespace warnings and 124837 leading whitespace
warnings when excluding *.md files (which obviously is in big part a
generator issue).  Others from that are generator related, I think those
need to be solved later.

The following patch just fixes up the easy case (trailing whitespace),
which could be easily automated:
for i in `find . -name \*.h -o -name \*.cc -o -name \*.c | xargs grep -l '[ 	]$' | grep -v testsuite/`; do sed -i -e 's/[ 	]*$//' $i; done
I've excluded files which I knew are obviously generated or go FE.

Is there anything else we'd want to avoid the changes?

Due to patch size, I've split it between gcc/ part (this patch)
and rest (include/, libiberty/, libgcc/, libcpp/, libstdc++-v3/).

    common block is made up of a series of segments that are joined one
    after the other.  In the linear system, a segment is a block
    diagonal.
- 
+
    To lay out a segment we first start with some variable and
    determine its length.  The first variable is assumed to start at
    offset one and extends to however long it is.  We then traverse the
    list of equivalences to find an unused condition that involves at
    least one of the variables currently in the segment.
- 
+
    Each equivalence condition amounts to the condition B+b=C+c where B
    and C are the offsets of the B and C variables, and b and c are
    constants which are nonzero for array elements, substrings or
    structure components.  So for

      EQUIVALENCE(B(2), C(3))
    we have
      B + 2*size of B's elements = C + 3*size of C's elements.
- 
+
    If B and C are known we check to see if the condition already
    holds.  If B is known we can solve for C.  Since we know the length
    of C, we can see if the minimum and maximum extents of the segment
    are affected.  Eventually, we make a full pass through the
    equivalence list without finding any new conditions and the segment
    is fully specified.
- 
+
    At this point, the segment is added to the current common block.
    Since we know the minimum extent of the segment, everything in the
    segment is translated to its position in the common block.  The
    usual case here is that there are no equivalence statements and the
    common block is series of segments with one variable each, which is
    a diagonal matrix in the matrix formulation.
- 
+
    Each segment is described by a chain of segment_info structures.  Each
    segment_info structure describes the extents of a single variable within
    the segment.  This list is maintained in the order the elements are
    positioned within the segment.  If two elements have the same starting
    offset the smaller will come first.  If they also have the same size their
