In order to handle TB's that translate to too much code, we
need to place the control of the length of the translation
in the hands of the code gen master loop.
Backports commit 8b86d6d25807e13a63ab6ea879f976b9f18cc45a from qemu
QEMU cannot pass through the breakpoints when 'si' command is used
in remote gdb. This patch disables inserting the breakpoints
when we are already single stepping though the gdb remote protocol.
This patch also fixes icount calculation for the blocks that include
breakpoints - instruction with breakpoint is not executed and shouldn't
be used in icount calculation.

While at it, use int for both num_insns and max_insns to make
sure we have same-type comparisons.
Backports commit b542683d77b4f56cef0221b267c341616d87bce9 from qemu
Rather than have a separate buffer of 10*max_ops entries,
give each opcode 10 entries. The result is actually a bit
smaller and should have slightly more cache locality.
