Update in V3:
1. Add -param=x86-stlf-window-ninsns= (default 64).
2. Exclude call in the window.
Since cfg is freed before machine_reorg, just do a rough calculation
of the window according to the layout.
Also according to an experiment on CLX, set window size to 64.

In 2021, Microchip launched two new series of AVR microcontrollers:
AVR-DA and AVR-DB. This patch-set contains patches to add support for
the full set of both series of devices, by listing the memory layouts in
avr-mcus.def.
There is an open GitHub Pull Request to add support for these devices to
eplace UNSPEC with RTL code for extendditi2.
When I submitted my patch on March 12th for extendditi2, Segher wished I
had removed the use of the UNSPEC for the vextsd2q instruction. This
patch rewrites extendditi2_vector to use VEC_SELECT rather than UNSPEC.
