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?

Extend STV pass to 64-bit mode
128-bit SSE load and store instructions can be used for load and store
of 128-bit integers if they are the only operations on 128-bit integers.
To convert load and store of 128-bit integers to 128-bit SSE load and
store, the original STV pass, which is designed to convert 64-bit integer
operations to SSE2 operations in 32-bit mode, is extended to 64-bit mode
in the following ways:
1. Class scalar_chain is turned into base class. The 32-bit specific
member functions are moved to the new derived class, dimode_scalar_chain.
The new derived class, timode_scalar_chain, is added to convert oad and
store of 128-bit integers to 128-bit SSE load and store.
2. Add the 64-bit version of scalar_to_vector_candidate_p and
remove_non_convertible_regs. Only TImode load and store are allowed
for conversion. If one instruction on the chain of dependent
instructions aren't TImode load or store, the chain of instructions
won't be converted.
3. In 64-bit, we only convert from TImode to V1TImode, which have the
same size. The difference is only vector registers are allowed in
TImode so that 128-bit SSE load and store instructions will be used
for load and store of 128-bit integers.
4. Put the 64-bit STV pass before the CSE pass so that instructions
changed or generated by the STV pass can be CSEed.
convert_scalars_to_vector calls free_dominance_info in 64-bit mode to
work around ICE in fwprop pass:

DWARF: turn dw_loc_descr_node field into hash map for frame offset check
As discussed on
<https://gcc.gnu.org/ml/gcc-patches/2016-02/msg01708.html>, this change
removes a field in the dw_loc_descr_node structure so we can get rid of
the CHECKING_P macro usage.
This field was used to perform consistency checks for frame offset in
DWARF procedures. As a replacement, this commit turns the "visited
nodes" set in resolve_args_picking_1 into a map that remembers for each
dw_loc_descr_node the frame offset associated to it, so that the
consistency check is still operational.
Boostrapped and regtested on x86_64-linux.
