    The constants named c0 and c1 turn up as macros in runtime.inc.  This
    reportedly breaks building on Solaris 11, where there is a system struct
    that has a field named c1.  The constants aren't needed by the runtime C
    code, so avoid the problem by grepping them out.

While changing LABEL_REF_LABEL it might as well become an inline
function, so that its clearer what types are involved.  Unfortunately
because it is still possible to use XEXP and related macros on a
LABEL_REF rtx you can still set the field to be a non insn rtx.  The
other unfortunate thing is that the generators actually create LABEL_REF
rtx that refer to MATCH_x rtx, so there we actually need to use XEXP to
bypass the checking this patch adds.

Tweak find_valid_class_1 to consider a reg class if atleast one regno in
that class is ok.

Previously, even if no regno was in_hard_reg_set_p, the code goes ahead and
considers rclass as valid. bad was set only if a regno was in the reg
class *and* HARD_REGNO_MODE_OK was false - if both were false, bad wasn't
set and the reload got a wrong rclass. If that happened to be the best
one, this eventually lead to find_reg running out of registers to
spill, because the chosen rclass wouldn't have enough regs.

Also, it expected every regno in rclass to be valid for mode 
i.e., if any regno fails HARD_REGNO_MODE_OK, it rejected the rclass. The
comments in the original commit for find_valid_class_1 say atleast one
regno is ok. This was updated to say "class which contains only
registers" when in_hard_reg_set_p was introduced in place of just
TEST_HARD_REG_BIT.

This commit fixes both of the above problems by not breaking out of the loop
on first unavailable regno. Instead, it computes the rclass size consisting
of all regnos in that class valid for the current mode. 

If that computed size is zero, the rclass would be skipped, as it won't 
beat best_size. Otherwise, the computed size is used to choose the best 
rclass, instead of the static size from reg_class_size.
