chain() -> get_chain()
chain_bit -> chain

The tdata1.dmode is defined at the same level of tdata1.type. As a
result, all triggers has a tdata1.dmode field (even the disabled
trigger).

With the above consideration, we move the tdata1.dmode checking and
setting to the same level of tdata1.type, i.e., in module_t.

dmode() -> get_dmode()
trigger_t.dmode_bit -> mcontrol_t.dmode

store() -> get_store()
store_bit -> store

load() -> get_load()
load_bit -> load

execute() -> get_execute(), execute_bit -> execute

structuralize trigger's tdata CSRs for modularization

Add tinfo register.

Not very interesting while spike only supports one trigger type,
but #1128 is about to change that. Without tinfo, it can become quite
slow for a debugger to discover which types are supported.

If a variable other than `i` is passed as `inx`, `VI_LOOP_ELEMENT_SKIP`
will still check `i` in the `else` case, ignoring `inx`.

Since `i` is the only value ever passed, drop the argument to avoid any
future confusion.

When resuming from debug mode, clear mstatus.MPRV if the new privilege mode is less than M-mode (#1149)

add suport for jvt: Table entries follow the current data endianness

Do not allow memory regions larger than (1ull << MAX_PADDR_BITS)

Other regions are inaccessible to the hardware being modeled

Fixes #1135

Add Spike support for Zvfh and Zvfhmin extensions

fix mevent_mask for Sscofpmf extension

fix print message of width=8 accesses

The mevent_mask of Sscofpmf depends on the support of privilege modes.
The UINH, SINH, VSINH, and VUINH are read-only 0 if unsupporting the
corresponding modes.
(https://github.com/riscv/riscv-count-overflow/issues/3#issuecomment-1291247070)

This commit fixes the mevent_mask of Sscofpmf accordingly. The previous
MHPMEVENTH_UINH is a typo, which should be MHPMEVENT_SINH instead.

Clean up dual-endian support

Set target endianess in constructors

The number of digits indicates the size of accesses. A size-1 access
needs two digits instead of one.
