Some scheduling descriptions, like the Cortex-A57 one, are reused for multiple -mcpu options.
Sometimes those other -mcpu cores support more architecture features than the Armv8-A Cortex-A57.
For example, the Cortex-A75 and Cortex-A76 support Armv8.2-A as well as the Dot Product instructions.
These Dot Product instructions have the neon_dot and neon_dot_q scheduling type, but that type is not
handled in cortex-a57.md, since the Cortex-A57 itself doesn't need to care about these instructions.
But if we just ignore the neon_dot(_q) type at scheduling we get really terrible codegen when compiling
for -mcpu=cortex-a76, for example, because the scheduler just pools all the UDOT instructions at the end
of the basic block, since it doesn't assume anything about their behaviour.
This patch ameliorates the situation somewhat by telling the Cortex-A57 scheduling model to treat any
insn that doesn't get assigned a cortex_a57_neon_type but is actually a is_neon_type instruction as
a simple neon_arith_basic instruction. This allows us to treat post-Armv8-A SIMD instructions more sanely
without having to model each of them explicitly in cortex-a57.md.
* config/arm/cortex-a57.md (cortex_a57_neon_type): Use neon_arith_basic
for is_neon_type instructions that have not already been categorized.

The function rs6000_force_indexed_or_indirect_mem makes a memory
operand suitable for indexed (or indirect) addressing. If the memory
address isn't yet valid, it loads the whole thing into a register to
make it valid. That isn't optimal. This changes it to load an
address that is the sum of two things into two registers instead.
This results in lower latency code, and if inside loops, a constant
term can be moved outside the loop.
* config/rs6000/rs6000.c (rs6000_force_indexed_or_indirect_mem):
Load both operands of a PLUS into registers separately.

We currently use subst definitions to handle the different variants of shift
count operands. Unfortunately, in the vector shift pattern the shift count
operand is used directly. Without it being adjusted for the 'subst' variants the
displacement value is omitted resulting in a wrong shift count being applied.
This patch needs to be applied to older branches as well.
