76824fb602 ppcmmu: skip over mode 1 entries when doing PAT flushes 
Mode 1 contains real addressing mode entries, which by definition cannot
be using segment registers. By skipping over them, we can shave off a
couple of seconds from the 10.2 boot time.

30afcb6ddc ppcmmu: Allow map dma for last byte of region. 
cur_dma_rgn->end is the last byte of a region. It is not the byte after the region. Therefore, subtract 1 from size before doing compare.

Also add more detail to the abort messages.

9ed1a118e6 ppcmmu: Check sizeof(T) explicitly. 
I don't know if the compiler is smart enough to figure out that ((guest_va & 0xFFF) + sizeof(T)) > 0x1000) is always false when sizeof(T) == 1 so we'll add a check for sizeof(T) > 1.

6582536591 Inline ppc_set_cur_instruction 
It's used in the main emulator loop (ppc_exec_inner), and the function
call overhead adds up.

By inlining it, time to boot to the Finder using a 7.1.2 install CD
and a 6100 ROM goes from ~6700ms to ~6400ms (with clang 14 on a
M2 Max)

35c86ad6bf Clean up #includes 
Result of running IWYU (https://include-what-you-use.org/) and
applying most of the suggestions about unncessary includes and
forward declarations.

Was motivated by observing that <thread> was being included in
ppcopcodes.cpp even though it was unused (found while researching
the use of threads), but seems generally good to help with build
times and correctness.

8348370142 Add separate flags for instruction and data TLBs.
