The insn_table is an array of constant structures and as such should be
declared const.
This change saves 1088 bytes of kernel text at the expense of 64 bytes
of kernel data on a pistachio_defconfig:
Before:
text data bss dec hex filename
7187103 1772760 470224 9430087 8fe447 vmlinux
After:
text data bss dec hex filename
7186015 1772824 470224 9429063 8fe047 vmlinux
