For rv128c shifts, a shamt of 0 is a shamt of 64, while for rv32c/rv64c
it stays 0 and is a hint instruction that does not change processor state.
For rv128c right shifts, the 6-bit shamt is in addition sign extended to
7 bits.

System headers may include templates if compiled with a C++ compiler,
which cause the compiler to complain if qemu/osdep.h is included
within a C++ source file's 'extern "C"' block. Add
an 'extern "C"' block directly to qemu/osdep.h, so that
system headers can be kept out of it.
There is a stray declaration early in qemu/osdep.h, which needs
to be special cased. Add a definition in qemu/compiler.h to
make it look nice.
config-host.h, CONFIG_TARGET, exec/poison.h and qemu/compiler.h
are included outside the 'extern "C"' block; that is not
an issue because they consist entirely of preprocessor directives.
This allows us to move the include of osdep.h in our two C++
source files outside the extern "C" block they were previously
using for it, which in turn means that they compile successfully
against newer versions of glib which insist that glib.h is
*not* inside an extern "C" block.

Here the disassembly of 0x120..0x13f is using the data that is in
0x104..0x123.
This is caused by passing the wrong value to the read_memory_func().
The intention is that at this point in the loop the 'cap_buf' buffer
already contains 'csize' bytes of data for the instruction at guest
addr 'pc', and we want to read in an extra 'tsize' bytes. Those
extra bytes are therefore at 'pc + csize', not 'pc'. On the first
time through the loop 'csize' happens to be zero, so the initial read
of 32 bytes into cap_buf is correct and as long as the disassembly
never needs to read more data we return the correct information.
Use the correct guest address in the call to read_memory_func().

ISA 3.0B added a set of Floating-Point Status and Control Register (FPSCR)
instructions: mffsce, mffscdrn, mffscdrni, mffscrn, mffscrni, mffsl.
This patch adds support for 'mffsl'.
'mffsl' is identical to 'mffs', except it only returns mode, status, and enable
bits from the FPSCR.
On CPUs without support for 'mffsl' (below ISA 3.0), the 'mffsl' instruction
will execute identically to 'mffs'.
Note: I renamed FPSCR_RN to FPSCR_RN0 so I could create an FPSCR_RN mask which
is both bits of the FPSCR rounding mode, as defined in the ISA.
I also fixed a typo in the definition of FPSCR_FR.
