Remove word_mode hack for split bitfields

This patch is effectively reverting a change from 1994.  The reason
I think it's a hack is that store_bit_field_1 is creating a subreg
reference to one word of a field even though it has already proven that
the field spills into the following word.  We then rely on the special
SUBREG handling in store_split_bit_field to ignore the extent of op0 and
look inside the SUBREG_REG regardless.  I don't see any reason why we can't
pass the original op0 to store_split_bit_field instead.

Tested on aarch64-linux-gnu and x86_64-linux-gnu.

gcc/
* expmed.c (store_bit_field_1): Do not restrict a multiword op0
to one word if the field is known to overlap other words.
(extract_bit_field_1): Likewise.
(store_split_bit_field): Remove compensating code.
(extract_split_bit_field): Likewise.

This patch adds support for the missing versions of the vec_mul altivec...

This patch adds support for the missing versions of the vec_mul 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 part of a series of patches to add them.

There aren't instructions for the {un}signed char, {un}signed short, and
{un}signed int versions of vec_mul so the output code is built from other
built-ins and operations that do have instructions.

The new test case is an executable test which verifies that the generated
code produces expected values. C macros were used so that the same
test case could be used for all the various supported types.

Bootstrapped and tested on powerpc64le-unknown-linux-gnu and
powerpc64-unknown-linux-gnu with no regressions. Is this ok for trunk?
