 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.
