We have found cases where pkt_has_store_s[01] is set incorrectly.
This leads to generating an unnecessary store that is left over
from a previous packet.
Add an attribute to determine if an instruction is a scalar store
The attribute is attached to the fSTORE macro (hex_common.py)
Update the logic in decode.c that sets pkt_has_store_s[01]

The imported files from the architecture library have added some
instruction attributes. Some of these will be used in a subsequent
patch for determing the size of a store.

Change SET_USR_FIELD to write to hex_new_value[HEX_REG_USR] instead
of hex_gpr[HEX_REG_USR].
Then, we need code to mark the instructions that can set implicitly
set USR
- Macros added to hex_common.py
- A_FPOP added in translate.c
Test case added in tests/tcg/hexagon/overflow.c
