064360e667 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.

77697d14e5 types.h: Use __builtin_bswap* with clang. 
clang pretends to be GCC 4.2 but we use __builtin_bswap* only with GCC 4.3+.
clang support __builtin_bswap*, so use it.

87ec3b7fa9 Don't continue to query block-size if disk doesn't have it.

94f701a826 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.

6a4ecd276e mips: Fix soft-float handling. 
Add -msoft-float alongside clang arguments to specify ABI.
Specify ABI in asm files explicitly.
This trigers asm warning due to gcc failing to propagate -msoft-float
but it's tolerable.

support the option.

345076a78a arm64: Fix compilation failure. 
Don't supply +nosimd to asm files.
Otherwise +nosimd coming from flags forbids some of instructions
used in cache_flush.

f034fab620 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.
