target-mips: fix decoding of microMIPS POOL32Axf instructions

Fix incorrect assumption that DSP and non-DSP versions of the following
instructions have the same encoding:
MULT, MULTU, MADD, MADDU, MSUB, MSUBU, MFHI, MFLO, MTHI, MTLO.
Correct the existing (non-DSP) instructions and add DSP equivalents....

target-mips: fix 34Kf configuration for DSP ASE

34Kf core does support DSP ASE.
CP0_Config3 configuration for 34Kf and description are wrong.

Please refer to MIPS32 34Kf(TM) Processor Core Datasheet

cpu: Partially revert "cpu: Change qemu_init_vcpu() argument to CPUState"

Commit c643bed99 moved qemu_init_vcpu() calls to common CPUState code.
This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed".

The reason for the failure is that CPUClass::kvm_fd is not yet...

target-mips: fix mipsdsp_mul_q31_q31

Multiplication of two fractional word elements is not correct when sign
extension/promotion is needed. This change fixes it by adding correct
casts from unsigned to signed values.
In addition, the tests (dpaq_sa_l_w.c and dpsq_sa_l_w.c) have been extended...

target-mips: Remove assignment to a variable which is never used

This assignment causes a compiler warning for compilations with the compiler
option -Wunused-but-set-variable (which is included with -Wextra).

Removing it allows using -Wextra for QEMU code without suppressing too many...

target-mips: fix mipsdsp_trunc16_sat16_round

This change corrects rounding and saturation of Q31 fractional value in
mipsdsp_trunc16_sat16_round(). Overflow detection was incorrect for the
corner case for PRECRQ_RS.PH, and this test case is also part of the change....

target-mips: fix branch in likely delay slot tcg assert

When a branch delay slot contains another branch instruction, the code
generated raises an exception, however since is_branch==1,
handle_delay_slot() doesn't get called immediately. This means
ctx->bstate isn't set to BS_BRANCH, and the decoder continues decoding...

target-mips: fix multiplication in mipsdsp_rndq15_mul_q15_q15

Multiplication of Q15 fractional halfword vectors was incorrect in the
previous implementation of mipsdsp_rndq15_mul_q15_q15. It failed to take
element signs into account. This change fixes it, and it adds a test case...

gdbstub: Replace GET_REG*() macros with gdb_get_reg*() functions

This avoids polluting the global namespace with a non-prefixed macro and
makes it obvious in the call sites that we return.

Semi-automatic conversion using, e.g.,
sed i 's/GET_REGL(/return gdb_get_regl(mem_buf, /g' target*/gdbstub.c...

Completes migration of target-specific code to new target-*/gdbstub.c.
