[PR55641] drop spurious const_type from reference_type variables
Although C++ reference types, denoted by DW_TAG_reference_type in
DWARFv2+ debug info, are unchangeable, we output names of reference type

TREE_READONLY. That's an internal implementation detail that shouldn't
leak to debug information. This patch fixes this.

[PR49366] emit loc exprs for C++ non-virtual pmf template value parms
We used to emit, in debug information, the values bound to pointer to
member function template parameters only when they were NULL or
virtual member functions, because those can be represented with
DW_AT_const_value.
In order to represent the symbolic pointer to member function
constants for non-virtual member functions, we'd need to be able to
emit relocations for part of DW_AT_const_value, which we don't. The
more viable alternative is to use DW_AT_location to represent such
values, as slated for inclusion in DWARFv5, according to
<URL:http://www.dwarfstd.org/ShowIssue.php?issue=130412.1>.
With this patch, when we can't emit a DW_AT_const_value, we emit each
"member" of the pointer to member function "record" as a
DW_OP_stack_value DW_OP_piece, as long as the referenced member
function is output in the same translation unit, otherwise we'd get
relocations to external symbols, something to avoid in debug sections.

REG_DEAD r159:SI
Inserting subreg reload before:
30: r164:SI=[r158:DI]
[snip]
Change to class FLOAT_REGS for r164
Well, that didn't do much. lra tried the equiv mem, found that didn't
work, and had to reload. Effectively getting back to the two original
insns but r159 replaced with r164. simplify_operand_subreg did not do
anything in this case because SLOW_UNALIGNED_ACCESS was true (wrongly
for power8, but that's beside the point). So now we have, using
abbreviated rtl notation:
r164:SI=[r158:DI]
r162:DI=unspec[fix(r164:SI)]
The problem here is that the first insn isn't valid, due to the rs6000
backend not supporting SImode in fprs, and r164 must be an fpr to make
the second insn valid.
next lra action:
Creating newreg=165 from oldreg=164, assigning class GENERAL_REGS to r165
30: r165:SI=[r158:DI]
Inserting insn reload after:
31: r164:SI=r165:SI
so now we have
r165:SI=[r158:DI]
r164:SI=r165:SI
r162:DI=unspec[fix(r164:SI)]
This ought to be good on power8, except for one little thing.
r165 is GENERAL_REGS so the first insn is good, a gpr load from mem.
r164 is FLOAT_REGS, making the last insn good, a fctiwz.
The second insn ought to be a sldi, mtvsrd, xscvspdpn combination, but
that is only supported for SFmode. So lra continue on reloading the
second insn, but in vain because it never tries anything other than
SImode and as noted above, SImode is not valid in fprs.
What this patch does is arrange to emit the two reloads needed for the
SLOW_UNALIGNED_ACCESS case at once, moving the subreg to the second
insn in order to switch modes, producing:
r164:SI=[r158:DI]
r165:SF=r164:SI#0
r162:DI=unspec[fix(r165:SF)]
I've also tidied a couple of other things:
1) "old" is unnecessary as it duplicated "operand".
2) Rejecting mem subregs due to SLOW_UNALIGNED_ACCESS only makes sense
if the original mode was not slow.

compiler: annotate or fix fall through cases in switch statements
A new GCC warning, -Wimplicit-fallthrough, detected these three cases
where a switch case falls through to another. One of them looks like
a bug, so I fixed it; the two other look like intended fall throughs
so I just added a "fall through" comment to suppress the GCC warning.
