3b163b0165 misc: Fix typos in comments
Codespell found and fixed these new typos:

* doesnt -> doesn't
* funtion -> function
* perfomance -> performance
* remaing -> remaining

A coding style issue (line too long) was fixed manually.

557d52fa69 target-ppc: Altivec 2.07: AES Instructions
This patch adds the Vector AES instructions introduced in Power ISA
Version 2.07:

   - Vector AES Cipher (vcipher)
   - Vector AES Cipher Last (vcipherlast)
   - Vector AES Inverse Cipher (vncipher)
   - Vector AES Inverse Cipher Last (vncipherlast)
   - Vector AES SubBytes (vsbox)

Note that the implementation of vncipher deviates from the RTL in
ISA V2.07.  However it does match the verbal description in the
third paragraph.  The RTL will be fixed in ISA V2.07B.  The
implementation here has been tested against actual P8 hardware.

6f3dab41fb target-ppc: Altivec 2.07: Doubleword Compares
This patch adds the Vector Compare Doubleword instructions introduced
by Power ISA Version 2.07:

  - Vector Compare Equal to Unsigned Doubleword (vcmpequd)
  - Vector Compare Greater Than Signed Doubleword (vcmpgtsd)
  - Vector Compare Greater Than Unsigned Doubleword (vcmpgtud)

These instructions are encoded with bit 31 set to 1 and so are duals with
vcmpeqfp, vcmpgtfp and vcmpbfp respectively.

The helper macro for integer compares is enhanced to account for 64-bit
operands.

818692ff95 target-ppc: Altivec 2.07: Change Bit Masks to Support 64-bit Rotates and Shifts
Existing code in the VROTATE, VSL and VSR macros for the Altivec rotate and shift
helpers uses a formula to compute a bit mask used to extract the rotate/shift
amount from the VRB register.  What is desired is:

    mask = (1 << (3 + log2(sizeof(element)))) - 1

but what is implemented is:

    mask = (1 << (3 + (sizeof(element)/2))) - 1

This produces correct answers when "element" is uint8_t, uint16_t or uint_32t.  But
it breaks down when element is uint64_t.

This patch corrects the situation.  Since the mask is known at compile time, the
macros are changed to simply accept the mask as an argument.

Subsequent patches in this series will add double-word variants of rotates and
shifts and thus take advantage of this fix.

is coded as a dual to vmulouw (bits 21-31 = 136).

aa9e930c88 target-ppc: Altivec 2.07: Change VMUL_DO to Support 64-bit Integers
This VMUL_DO macro provides support for the various vmule* and vmulo*
instructions.  These instructions multiply vector elements, producing
products that are one size larger; e.g. vmuleub multiplies unsigned 8-bit
elements and produces a 16 bit unsigned element.

The existing macro works correctly for the existing instructions (8-bit,
and 16-bit source elements) but does not work correctly for 32-bit
source elements.

This patch adds an explicit cast to the multiplicands, forcing them to be
of the target element type.  This is required for the forthcoming patches
that add the vmul[eo][us]w instructions.
