The gf128mul_x_ble function is currently defined in gf128mul.c, because it depends on the gf128mul_table_be multiplication table. However, since the function is very small and only uses two values from the table, it is better for it to be defined as inline function in gf128mul.h. That way, the function can be inlined by the compiler for better performance. For consistency, the other gf128mul_x_* functions are also moved to the header file. In addition, the code is rewritten to be constant-time. After this change, the speed of the generic 'xts(aes)' implementation increased from ~225 MiB/s to ~235 MiB/s (measured using 'cryptsetup benchmark -c aes-xts-plain64' on an Intel system with CRYPTO_AES_X86_64 and CRYPTO_AES_NI_INTEL disabled).
