This patch improves exception handling in MIPS.
Instructions generate several types of exceptions.
When exception is generated, it breaks the execution of the current translation
block. Implementation of the exceptions handling does not correctly
restore icount for the instruction which caused the exception. In most cases
icount will be decreased by the value equal to the size of TB.
This patch passes pointer to the translation block internals to the exception
handler. It allows correct restoring of the icount value.
v3 changes:
This patch stops translation when instruction which always generates exception
is translated. This improves the performance of the patched version compared
to original one.
