target/arm: Use TCF0 and TFSRE0 for unprivileged tag checks
...
Section D6.7 of the ARM ARM states:
For the purpose of determining Tag Check Fault handling, unprivileged
load and store instructions are treated as if executed at EL0 when
executed at either:
- EL1, when the Effective value of PSTATE.UAO is 0.
- EL2, when both the Effective value of HCR_EL2.{E2H, TGE} is {1, 1}
and the Effective value of PSTATE.UAO is 0.
ARM has confirmed a defect in the pseudocode function
AArch64.TagCheckFault that makes it inconsistent with the above
wording. The remedy is to adjust references to PSTATE.EL in that
function to instead refer to AArch64.AccessUsesEL(acctype), so
that unprivileged instructions use SCTLR_EL1.TCF0 and TFSRE0_EL1.
The exception type for synchronous tag check faults remains unchanged.
This patch implements the described change by partially reverting
commits 50244cc76abc and cc97b0019bb5.

target/arm: Speed up aarch64 TBL/TBX
...
Always perform one call instead of two for 16-byte operands.
Use byte loads/stores directly into the vector register file
instead of extractions and deposits to a 64-bit local variable.
In order to easily receive pointers into the vector register file,
convert the helper to the gvec out-of-line signature. Move the
helper into vec_helper.c, where it can make use of H1 and clear_tail.
