[RS6000] TARGET_RELOCATABLE

For ABI_V4, -mrelocatable and -fPIC both generate position independent
code, with some extra "fixup" output for -mrelocatable.  The
similarity of these two options has led to the situation where the
sysv4.h SUBTARGET_OVERRIDE_OPTIONS sets flag_pic on seeing
-mrelocatable, and sets TARGET_RELOCATABLE on seeing -fPIC.  That
prevents LTO from properly optimizing position dependent executables,
because the mutual dependence of the flags and the fact that LTO
streaming records the state of rs6000_isa_flags, result in flag_pic
being set when it shouldn't be.

So, don't set TARGET_RELOCATABLE when -fPIC.  Places that currently
test TARGET_RELOCATABLE can instead test
TARGET_RELOCATABLE || (DEFAULT_ABI == ABI_V4 && flag_pic > 1)
or since TARGET_RELOCATABLE can only be enabled when ABI_V4,
DEFAULT_ABI == ABI_V4 && (TARGET_RELOCATABLE || flag_pic > 1).

Also, since flag_pic is set by -mrelocatable, a number of places that
currently test TARGET_RELOCATABLE can be simplified.  I also made
-mrelocatable set TARGET_NO_FP_IN_TOC, allowing TARGET_RELOCATABLE to
be removed from ASM_OUTPUT_SPECIAL_POOL_ENTRY_P.  Reducing occurrences
of TARGET_RELOCATABLE is a good thing.

cfgcleanup: Fold jumps and conditional branches with returns

This patch makes cfgcleanup optimize jumps to returns.  There are three
cases this handles:

-- A jump to a return; this is simplified to just that return.
-- A conditional branch to a return; simplified to a conditional return.
-- A conditional branch that falls through to a return.  This is simplified
   to a conditional return (with the condition inverted), falling through
   to a jump to the original destination.  That jump can then be optimized
   further, as usual.

This handles all cases the current function.c does, and a few it misses.

PR c++/62314: C++: add fixit hint to misspelled member names

When we emit a hint about a misspelled member name, it will slightly
aid readability if we use a fixit-hint to show the proposed
name in context within the source code (and in the future this
might support some kind of auto-apply in an IDE).

This patch adds such a hint to the C++ frontend, taking us from:

test.cc:10:15: error: 'struct foo' has no member named 'colour'; did you mean 'color'?
   return ptr->colour;
               ^~~~~~

to:

test.cc:10:15: error: 'struct foo' has no member named 'colour'; did you mean 'color'?
   return ptr->colour;
               ^~~~~~
