Przemyslaw Wirkus dd4a72c859 aarch64: Add CSR PDEC instruction 
This patch adds:
+ New feature +csre to -march command line.
+ New instruction CSR PDEC associated with CSRE feature.

Please note that CSRE system registers were already upstreamed. This patch
should finalize CSRE feature implementation.

CSRE feature adds CSR PDEC (Decrements Call stack pointer by the size of
a Call stack record) instruction. Although this instruction has operand
(PDEC) it's instruction's only operand. PDEC forces instruction field Rt
to be set to 0b1111. This results in fixed opcode of the instruction.
