GCC expands switch statements in a very simplistic way and tries to use a table...

GCC expands switch statements in a very simplistic way and tries to use a table
expansion even when it is a bad idea for performance or codesize.
GCC typically emits extremely sparse tables that contain mostly default entries
(something which currently cannot be tuned by backends).  Additionally the
computation of the minimum/maximum label offsets is too simplistic so the
tables are often twice as large as necessary.

The cost of a table switch is significant due to the setup overhead, the table
lookup (which due to being sparse and large adds unnecessary cachemisses)
and hard to predict indirect jump.  Therefore it is best to avoid using a table
unless there are many real case labels.

This patch fixes that by setting the default aarch64_case_values_threshold to
16 when the per-CPU tuning is not set.  On SPEC2006 this improves the switch
heavy benchmarks GCC and perlbench both in performance (1-2%) as well as size
(0.5-1% smaller).

    gcc/

Return a better case_values_threshold when optimizing.

SIMD operations like combine prefer to have their operands in FP registers,

This patch adds support for the vec_cmpne altivec builtins from the Power...

This patch adds support for the vec_cmpne 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 vec_cmpne so the output code is built from other
built-ins that do have instructions which in this case is the following.

vec_cmpneq (va, vb) == vec_nor (vec_cmpeq (va, vb), vec_cmpeq (va, vb))

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 of various
basic types. A separate executable test case is used for the long long versions
of vec_cmpne because of some differences in loading and storing the vectors.

* config/rs6000/altivec.h (vec_cmpne): Add #define for vec_cmpne.
