C code or compiler built-ins are preferable over inline assembler for

As with f64c2e710fa1a7b59753224e717f57c48462076f for x86 and Arm,
this removes the inline assembler on GCC (and Clang) since we now
require recent enough compiler versions (this indeed seems to work on
AArch64).

As you are writing that this preferrable for better optimisations
Please provide benchmarks (for sh4, avr32)
This is a ridiculous request, considering nobody has such hardware at all.
thx
