Mohit K. Bhakkad e8659b5df6 [LLDB][MIPS] Add MIPS32 and MIPS64 core revisions
Patch by Jaydeep Patil

Added MIPS32 and MIPS64 core revisions. This would be followed by register context and emulate-instruction for MIPS32.

DYLDRendezvous.cpp:
On Linux link map struct does not contain extra load offset field.

Tamas Berghammer e7708688ba Fix signle stepping on arm when multiple thread is involved
On linux-arm we use software single stepping where setting the new
breakpoint is only possible while the process is in stopped state.
This CL moves the setup code for single stepping form the SigneStep
operation into the Resum method to avoid an error when the process
already started when we want to step one of the thread.

Pavel Labath bd7cbc5a97 NativeProcessLinux: Merge operation and monitor threads
Summary:
This commit moves the functionality of the operation thread into the new monitor thread. This is
required to avoid a kernel race between the two threads and I believe it actually makes the code
cleaner.

Test Plan: Ran the test suite a couple of times, no regressions.

Tamas Berghammer c4ddfd865d Auto advance pc for signle stepping on arm when emulation failes
The arm instruction emulation handles only some of the opcode (including
all of them modifying the PC). For the rest of the instructions we can
advance the PC by the size of the instruction as they don't modify the
PC on any other way.

Pavel Labath 1107b5a597 Use non-blocking waitpid in NativeProcessLinux
Summary:
This is the first phase of the merging of Monitor and Operation threads in NativeProcessLinux
(which is necessary since the two threads race inside Linux kernel). Here, I reimplement the
Monitor thread do use non-blocking waitpid calls, which enables later addition of code from the
operation thread.

Test Plan: Ran the test suite a couple of times, no regressions detected.

Tamas Berghammer d8c338d42f Add single stepping logic for linux arm
Linux arm don't support hardware stepping (neither mismatch
breakpoints). This patch implement signle stepping with doing a software
emulation of the next instruction and then setting a temporary
breakpoint at the address where the thread will stop next.

Tamas Berghammer adf8adbd77 Fix wrong type convesrion in ReadRegOperation
The automatic conversion from long int to lldb::addr_t caused sign
extension but for a register read it is an unwanted behaviour. Fix with
forcing different conversion path.

Tamas Berghammer 7cb18bf537 Fetch module specification from remote process also
Previously the remote module sepcification was fetched only from the
remote platform. With this CL if we have a remote process then we ask it
if it have any information from a given module. It is required because
on android the dynamic linker only reports the name of the SO file and
the platform can't always find it without a full path (the process can
do it based on /proc/<pid>/maps).
