Matheus Tavares Bernardino e1b526f1d8 Hexagon: add PC alignment check and exception 
The Hexagon Programmer's Reference Manual says that the exception 0x1e
should be raised upon an unaligned program counter. Let's implement that
and also add some tests.

/*
* Section 5.5 of the Hexagon V67 Programmer's Reference Manual
*
* Slot 1 store with slot 0 load
* A slot 1 store operation with a slot 0 load operation can appear in a packet.
* The packet attribute :mem_noshuf inhibits the instruction reordering that
* would otherwise be done by the assembler. For example:
* {
* memw(R5) = R2 // slot 1 store
* R3 = memh(R6) // slot 0 load
* }:mem_noshuf
* Unlike most packetized operations, these memory operations are not executed
* in parallel (Section 3.3.1). Instead, the store instruction in Slot 1
* effectively executes first, followed by the load instruction in Slot 0. If
* the addresses of the two operations are overlapping, the load will receive
* the newly stored data. This feature is supported in processor versions
* V65 or greater.
*
*
* For qemu, we look for a load in slot 0 when there is a store in slot 1
* in the same packet. When we see this, we call a helper that probes the
* load to make sure it doesn't fault. Then, we process the store ahead of
* the actual load.
