Factor out division by squares
...
This patch implements the some of the division optimizations discussed in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71026 .
The division reciprocal optimization now handles divisions by squares:
x / (y * y) -> x * (1 / y) * (1 / y)
This requires at least one more division by y before it triggers - the
3 divisions of (1/ y) are then CSEd into a single division. Overall
this changes 1 division into 1 multiply, which is generally much faster.

This patch adds support for modelling the varying costs of
different addressing modes. The generic cost table treats
all addressing modes as having equal cost.

[ARM] Refactor costs calculation for MEM.
...
This patch moves the calculation of costs for MEM into a
separate function, and reforms the calculation into two
parts. Firstly any additional cost of the addressing mode
is calculated, and then the cost of the memory access itself
is added.
In this patch, the calculation of the cost of the addressing
mode is omitted, to be added in a subsequent patch.
