Remove libgcc dependency.
...
libgcc for boot environment isn't always present and compatible.
libgcc is often absent if endianness or bit-size at boot is different
from running OS.
libgcc may use optimised opcodes that aren't available on boot time.
So instead of relying on libgcc shipped with the compiler, supply
the functions in GRUB directly.
Tests are present to ensure that those replacement functions behave the
way compiler expects them to.

crypto: restrict cipher block size to power of 2.

All current ciphers have blocks which are power of 2 and it's
unlikely to change. Other block length would be tricky to handle anyway.
This restriction allows avoiding extra divisions.

Supply signed division to fix ARM compilation.

Previously we supplied only unsigned divisions on platforms that need software
division.
Yet compiler may itself use a signed division. A typical example would be a
difference between 2 pointers which involves division by object size.

diskfilter: fix crash in validate_lv for mdraid arrays
...
Commit 750f4bacd3
put LV validation before
actual vg assignment. Make grub_diskfilter_make_raid to assign ->vg as
happens in other cases for consistency. Also clean up redundant code and add
explicit NULL lv->vg check in validate_lv.
Also fix segment validation in validate_lv; it became obvious when crash
was fixed.
