[PATCH v2 0/9] target/arm: Convert 2-reg-shift and 1-reg-imm Neon insns to decodetree

[Peter Maydell]

This patchset converts the Neon insns in the 2-register-and-shift-amount
and 1-register-and-modified-immediate groups to decodetree.

Changes since v1:
 * old patch 1 is now in master
 * patch 1, 2, 3, 4: create and use separate formats for each size of shift
 * patch 5, 6, 7: use new @2reg_shrn_[dsh] formats and keep Q bit in the
   per-insn decode rather than folding it into the format
 * patch 8: use %neon_rshift_i5 in new @2reg_vcvt format
 * patch 9: various changes

Patches still needing review: 1, 5, 9.  (RTH: you might want to look over
2 as well: I didn't use quite the same shift formats you suggested.)

thanks
