Log Message:
gcc/arm: For -mtp=soft, ensure stack alignment in leaf functions using
thread local storage.

For each function compiled, record whether it accesses thread-local
storage.  When laying out the stack frame for a leaf function, if the
function needs to use a C runtime subroutine to retrieve the thread
pointer, make sure that the stack pointer is aligned appropriately.
