Some ARM implementaions, e.g. A-series, does return stack prediction. That is,
...
the processor keeps a return addresses stack (RAS) which stores the address
and the instruction execution state of the instruction after a function-call
type branch instruction.
Calling a "noreturn" function with normal call instructions (e.g. bl) can
corrupt RAS and causes 100% return misprediction so LLVM should use a
unconditional branch instead. i.e.
mov lr, pc
b _foo
The "mov lr, pc" is issued in order to get proper backtrace.

Enable ARM base pointer when calling functions with large arguments.
...
When an outgoing call takes more than 2k of arguments on the stack, we
don't allocate that call frame in the prolog, but adjust the stack
pointer immediately before the call instead.
This causes problems with the emergency spill slot because PEI can't
track stack pointer adjustments on the second pass, and if the outgoing
arguments are too big, SP can't be used to reach the emergency spill
slot at all.
Work around these problems by ensuring there is a base or frame pointer
that can be used to access the emergency spill slot.

Fixed an error where if we tried to format a ValueObject using a format
that was incorrect for a variable, then it would set ValueObject::m_error
to an error state and stop the value from being able to be updated. We now
leave m_error alone and only let the update value code change that. Any errors
in formatting will return a valid value as C string that contains an error
string. This lets us then modify the format and redisplay without any issues.

ARM BL/BLX instruction fixups should use relocations.

We on the linker to resolve calls to the appropriate BL/BLX instruction
to make interworking function correctly. It uses the symbol in the

unconditional-branch fixups.
