Hi,
this series fixes translation for opcodes crossing page boundary and adds a
testcase.

If TB ends with an opcode that crosses page boundary and the following
page is not executable then EPC1 for the code fetch exception wrongly
points at the beginning of the TB. Always treat instruction that crosses
page boundary as a separate TB.

Don't generate TCG operations when privilege, register window or
coprocessor checks fail.

Record last valid 4-register window pane number in TB flags so that a
window overflow exception throw point is known at the translation time.

Hi,
this series moves decision about throwing window overflow exception to
translation phase and stops code generation early when privilege, window
overflow or coprocessor exception is thrown.
LTP test suite with this series applied runs 6% faster.
