99097cab4c Add implementation of access to the ARM SPSR register. (#1178)
The SPSR register is named within the Unicorn headers, but the code
to access it is absent. This means that it will always read as 0 and
ignore writes. This makes it harder to work with changes in processor
mode, as the usual way to return from a CPU exception is a
`MOVS pc, lr` for undefined instructions or `SUBS pc, lr, #4`
for most other aborts - which implicitly restores the CPSR from SPSR.

This change adds the access to the SPSR so that it can be read and
written as the caller might expect.

b59632fb64 Ensure that PC is not fixed up when code tracing or timing. (#1179)
Under some circumstances, the PC is not fixed up properly when
returning from the execution of a block in cpu_tb_exec. This appears
to be caused by the resetting of the PC from the tb.

This change removes the additional fixup in the cases where there
is code tracing or timing active. Either of these cases would result
in the wrong PC being reported.

Closes unicorn-engine#1105.

626d72d6df Two fixes to get unicorn build better with MSVC. (#1136)
* Change MSVC keywords.

all of them allows a successful compilation under VC 2017 (15.9).

* Switch from /ZI to /Zi to avoid crashes at longjmp in debug builds.

* Adding regression test for issue where writing memory into a read only segment during a access callback fails.

02e6c14e12 x86: add MSR API via reg API (#755)
Writing / reading to model specific registers should be as easy as
calling a function, it's a bit stupid to write shell code and run them
just to write/read to a MSR, and even worse, you need more than just a
shellcode to read...

So, add a special register ID called UC_X86_REG_MSR, which should be
passed to uc_reg_write()/uc_reg_read() as the register ID, and then a
data structure which is uc_x86_msr (12 bytes), as the value (always), where:
	Byte	Value		Size
	0	MSR ID		4
	4       MSR val		8
