This commit was created with scripts/clean-includes.
All .c should include qemu/osdep.h first. The script performs three
related cleanups:
* Ensure .c files include qemu/osdep.h first.
* Including it in a .h is redundant, since the .c already includes
it. Drop such inclusions.
* Likewise, including headers qemu/osdep.h includes is redundant.
Drop these, too.

commit fb3f3730e4 added mechanism to generate virtual instruction
exception during instruction decode when virt is enabled.
However in some situations, illegal instruction exception can be raised
due to state of CPU. One such situation is implementing branch tracking.
[1] An indirect branch if doesn't land on a landing pad instruction, then
cpu must raise an illegal instruction exception.
Implementation would raise such expcetion due to missing landing pad inst
and not due to decode. Thus DisasContext must have `virt_inst_excp`
initialized to false during DisasContxt initialization for TB.

The implementation does not have much functionality (besides accepting

the hart executes in the required privilege level for the instruction),
as QEMU does not model CPU caches and instructions are documented
to not raise any exceptions.

We should call decode_save_opc() for all relevant instructions which
can potentially generate a virtual instruction fault or a guest page
fault because generating transformed instruction upon guest page fault
expects opcode to be available. Without this, hypervisor will see
transformed instruction as zero in htinst CSR for guest MMIO emulation
which makes MMIO emulation in hypervisor slow and also breaks nested
virtualization.

Mark up the sysreg definitions for the system instructions
trapped by HFGITR bits 18..47. These bits cover TLBI
TLB maintenance instructions.
(If we implemented FEAT_XS we would need to trap some of the
instructions added by that feature using these bits; but we don't
yet, so will need to add the .fgt markup when we do.)

Mark up the sysreg definitions for the registers trapped
by HDFGRTR/HDFGWTR bits 12..x.
Bits 12..22 and bit 58 are for PMU registers.
The remaining bits in HDFGRTR/HDFGWTR are for traps on
registers that are part of features we don't implement:
Bits 23..32 and 63 : FEAT_SPE
Bits 33..48 : FEAT_ETE
Bits 50..56 : FEAT_TRBE
Bits 59..61 : FEAT_BRBE
Bit 62 : FEAT_SPEv1p2.
