tcg: Fix do_nonatomic_op_* vs signed operations

The smin/smax/umin/umax operations require the operands to be
properly sign extended.  Do not drop the MO_SIGN bit from the
load, and additionally extend the val input.

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.

e54cf7ee03 find_ram_offset optimization 
The ram_offset allocator searches the smalest gap in the ram_offset address space.
This is slow especialy in combination with many allocation (i.e. snapshots). When
it is known that there is no gap, this is now optimized.

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.

074566cf69 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.

4055a5ab10 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.

Add uc_ctl_get/set_tcg_buffer_size 
We still need this API because the virtual memory address space of

32 bits os is only 4GB and we default need 1G per instance

fails check if emulation is running before jump out of the emulated code.
