target-arm: Implement AArch64 views of fault status and data registers

Browse source 
Implement AArch64 views of ESR_EL1 and FAR_EL1, and make the 32 bit
DFSR, DFAR, IFAR share state with them as architecturally specified.
The IFSR doesn't share state with any AArch64 register visible at EL1,
so just rename the state field without widening it to 64 bits.

[PMM: Minor tweaks; fix some bugs involving inconsistencies between
 use of offsetof() or offsetoflow32() and struct field width]
