[RS6000] Allow saving of fixed regs.
As I noted a long time ago in the comment on fixed_reg_p, the real
problem with saving fixed/global regs is that exception frame
unwinding might restore them. So don't emit eh_frame info for any
such reg, and the unwinder won't restore them.
Also, tidy rs6000_savres_strategy. Delaying some checks means we
won't iterate over regs quite so often.

ira.c validate_equiv_mem
This function is used to validate REG_EQUIV notes generated by ira,
and to validate potential insn combines performed by ira. The two
conditions are not exactly the same, with reload being more
restrictive. Separate them so more combines/moves can occur.
For example, this sequence from cfgexpand.c:expand_gimple_cond

ira.c combine_and_move_insns, and ordering of functions
Notes added by add_store_equivs are not used directly or indirectly by
combine_and_move_insns. add_store_equivs can therefore run later
without affecting the output of combine_and_move_insns, and thus
add_store_equivs need not take into account potentially moved insns.
Since not all potentially combined/moved insns are in fact combined or
moved, this may allow add_store_equivs to add more REG_EQUIV notes.
grow_reg_equivs isn't needed until the reload reg_equivs array is
changed.

S/390: Replace LDER with LDR.
For performance reasons it is important to write the full 64 bits of
an FPR target reg even when dealing with 32 bit values. So we chose
lder over ler for 32 bit float register moves. lder zero-extends the
32 bit value from the source reg to 64 bit in the target. However,
since it actually doesn't matter whether we write the upper 32 bits
with zeros or with any other garbage we can also use ldr instead. It
is bit shorter and therefore will do good for I-Cache usage.

S/390: Memory constraint cleanup
This fixes an issue with the long displacement memory address
constraints S and T. These were defined to only accept long
displacement addresses. This is wrong since a memory constraint must
not reject an address with a 0 displacement. Reload relies on being
able to turn an invalid memory address into a valid one by reloading
the address into a base register. The S and T constraints would
reject such an address.
This isn't really a problem for the backend since we used the
constraints with that knowledge there but it is a problem for people
writing inline assemblies.

This patch adds support for the signed and unsigned int versions of the...
This patch adds support for the signed and unsigned int versions of the
vec_adde altivec builtins from the Power Architecture 64-Bit ELF V2 ABI
OpenPOWER ABI for Linux Supplement (16 July 2015 Version 1.1). There are
many of the builtins that are missing and this is the first of a series
of patches to add them.
There aren't instructions for the int versions of vec_adde so the
output code is built from other built-ins that do have instructions
which in this case is just two vec_adds with a vec_and to ensure the
carry vector is comprised of only the values 0 or 1.
The new test cases are executable tests which verify that the generated
code produces expected values. C macros were used so that the same
test case could be used for both the signed and unsigned versions. An
extra executable test case is also included to ensure that the modified
support for the __int128 versions of vec_adde is not broken. The same
test case could not be used for both int and __int128 because of some
differences in loading and storing the vectors.
Bootstrapped and tested on powerpc64le-unknown-linux-gnu with no
regressions. Is this ok for trunk?
