target/i386: fix operand order for PDEP and PEXT
For PDEP and PEXT, the mask is provided in the memory (mod+r/m)
operand, and therefore is loaded in s->T0 by gen_ldst_modrm.
The source is provided in the second source operand (VEX.vvvv)
and therefore is loaded in s->T1. Fix the order in which
they are passed to the helpers.

target/i386: Verify memory operand for lcall and ljmp
These two opcodes only allow a memory operand.
Lacking the check for a register operand, we used the A0 temp
without initialization, which led to a tcg abort.

Slight refactoring to reduce code duplication.
...
This also comes with a performance bump due to inlining of reg_read/reg_write
(as they're only called once now) and the unlikely() on CHECK_REG_TYPE.

Implement uc_reg_{read,write}{,_batch}2 APIs.

These APIs take size parameters, which can be used to properly bounds-check the
inputs and outputs for various registers. Additionally, all backends now throw
UC_ERR_ARG if the input register numbers are invalid.
Completes #1831 .

Remove MMU hacks
...
Unicorn has included some ugly hacks to provide a envirement where vaddr == paddr.
These hacks where to use the full 64 bit mappings on x86 without init the mmu
and some memory redirect for MIPS.
The UC_TLB_CPU mode defaults to vaddr == paddr, therfor these hacks aren't
required anymore.

difference between stop_request and quit_request

quit_request is for internal use. This means the IP register was updated and
qemu needs to rebuild the translation blocks.
stop_request is set by the user (uc_emu_stop) to indecate that unicorn sould
stop emulating.
