a702c5339e target/ppc: Implement xxm[tf]acc and xxsetaccz
Implement the following PowerISA v3.1 instructions:
xxmfacc: VSX Move From Accumulator
xxmtacc: VSX Move To Accumulator
xxsetaccz: VSX Set Accumulator to Zero

The PowerISA 3.1 mentions that for the current version of the
architecture, "the hardware implementation provides the effect of ACC[i]
and VSRs 4*i to 4*i + 3 logically containing the same data" and "The
Accumulators introduce no new logical state at this time" (page 501).
For now it seems unnecessary to create new structures, so this patch
just uses ACC[i] as VSRs 4*i to 4*i+3 and therefore move to and from
accumulators are no-ops.

eb69a84bb0 target/ppc: Use TCG_CALL_NO_RWG_SE in fsel helper
fsel doesn't change FPSCR and CR1 is handled by gen_set_cr1_from_fpscr,
so helper_fsel doesn't need the env argument and can be declared with
TCG_CALL_NO_RWG_SE. We also take this opportunity to move the insn to
decodetree.

1f26c75191 PPC64/TCG: Implement 'rfebb' instruction
An Event-Based Branch (EBB) allows applications to change the NIA when a
event-based exception occurs. Event-based exceptions are enabled by
setting the Branch Event Status and Control Register (BESCR). If the
event-based exception is enabled when the exception occurs, an EBB
happens.

The following operations happens during an EBB:

- Global Enable (GE) bit of BESCR is set to 0;
- bits 0-61 of the Event-Based Branch Return Register (EBBRR) are set
to the the effective address of the NIA that would have executed if the EBB
didn't happen;
- Instruction fetch and execution will continue in the effective address
contained in the Event-Based Branch Handler Register (EBBHR).

The EBB Handler will process the event and then execute the Return From
Event-Based Branch (rfebb) instruction. rfebb sets BESCR_GE and then
redirects execution to the address pointed in EBBRR. This process is
described in the PowerISA v3.1, Book II, Chapter 6 [1].

This patch implements the rfebb instruction. Descriptions of all
relevant BESCR bits are also added - this patch is only using BESCR_GE,
but the next patches will use the remaining bits.

Additionally, REQUIRE_64BIT when L=1 to match what is specified in The
Programming Environments Manual:

"For 32-bit implementations, the L field must be cleared, otherwise the
instruction form is invalid."

Some CPUs are known to deviate from this specification by ignoring the
L bit [1]. The stricter behavior, however, can help users that test
software with qemu, making it more likely to detect bugs that would
otherwise be silent.

If deemed necessary, a future patch can adapt this behavior based on
the specific CPU model.

[1] The 601 manual is the only one I've found that explicitly states
that the L bit is ignored, but we also observe this behavior in a 7447A
v1.2.
