ARM: net: JIT compiler for packet filters

based of Matt Evans's PPC64 implementation.

The compiler generates ARM instructions but interworking is
supported for Thumb2 kernels.

Supports both little and big endian. Unaligned loads are emitted
for ARMv6+. Not all the BPF opcodes that deal with ancillary data
are supported. The scratch memory of the filter lives on the stack.
Hardware integer division is used if it is available.

Enabled in the same way as for x86-64 and PPC64:

	echo 1 > /proc/sys/net/core/bpf_jit_enable

A value greater than 1 enables opcode output.

---

Changes in v7:
 * fix the intruction generation for LDX_MSH, OR_X, LSH_K,
   RSH_K and JMP_JA
 * fix the condition for saving the A register
 * use fls() instead of the compiler builtin
 * punt to the interpreter on absolute loads with K < 0
 * check for invalid data references
 * support the NEG opcode
 * clear X in the prologue based on a context flag
 * simplify the conditional jumps

Changes in v6:
 * fix the code generation for the ANC_CPU opcode

Changes in v5:
 * replace SEEN_LEN with SEEN_SKB
 * set ctx->seen when handling some ancillary data opcodes

Changes in v4:
 * first check if the JIT compiler is enabled
 * fix the code generation for the LDX_MSH opcode

Changes in v3:
 * no longer depend on EABI and !Thumb2
 * add BLX "emulation" for ARMv4 without Thumb
 * use the integer divide instruction on Cortex-A15
 * fix the handling of the DIV_K opcode
 * use a C wrapper for __aeabi_uidiv
 * fix the generation of the epilogue (non-FP case)

Changes in v2:
 * enable the compiler only for ARMv5+ because of the BLX instruction
 * use the same comparison for the ARM version checks
 * use misaligned accesses on ARMv6
 * fix the SEEN_MEM
 * fix the mem_words_used()
