[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.

Also, I think a ZERO_EXTEND of a vector mode could in principle satisfy

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:
