Backport 10b8eb94c0 
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.

b041345a73 Fix RISCV test_riscv32_fp_move test 
RISCV FP registers are 64-bit in size, even in 32-bit mode, because they can
hold doubles. The test even uses the double-precision instruction fmv.d. Thus,
the reads should be reading 64-bit registers.

30d202b89e Simplify reg_read/reg_write, obtaining a perf boost. 
Single reg_read/reg_write is now about 25% faster.

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.

a998231a0e Fix sample_ctl.py. 
Commit 640251e1aa added a size parameter to uc_hook_tcg_op_2, but this was not
reflected in the Python bindings.

Commit fbf4078d65 added a len parameter to ctl_remove_cache, but this was not
reflected in sample_ctl.py.
