* inssel-x86.brg:
  MONO_EMIT_NEW_X86_COMPARE_MEMBASE_(REG/IMM) -- emit the opcode cmp
[membase], (reg/imm)
  MONO_EMIT_BOUNDS_CHECK[_IMM] -- override the generic version with an
x86 specific version.
* inssel.brg:
  MONO_EMIT_BOUNDS_CHECK[_IMM] -- a new macro that checks for array
bounds. A arch can override this if it is able to provide a version
faster than the default.
  OP_GETCHR, CEE_LDELEMA -- use the above macro.

As usual, you *must* provide a ChangeLog entry for your changes.

Do not even wait for me to ask for the ChangeLog entry, you are only
adding latency to the approval process.
