Now that the libgfortran ABI major version has been bumped, we can
remove functions for which the frontend nowadays generates inline
code.

This removes the malloc, free, exponent, fraction, nearest, rrspacing,
spacing, set_exponent and transpose intrinsics. Also the unused
store_exe_path function is removed.

The negdi2 patterns for ARM and Thumb-2 are duplicated because Thumb-2 doesn't support RSC with an immediate.

The negdi2 patterns for ARM and Thumb-2 are duplicated because Thumb-2
doesn't support RSC with an immediate.  We can however emulate RSC with
zero using a shifted SBC.  If we add this to subsi3_carryin the negdi
patterns can be merged, simplifying things a bit.  This should generate
identical code in all cases.

Thumb uses a special register allocation order to increase the use of low
registers.  Oddly enough, LR appears before R12, which means that LR must
be saved and restored even if R12 is available.  Swapping R12 and LR means
this simple example now uses R12 as a temporary (just like ARM):

int f(long long a, long long b)
{
  if (a < b) return 1;
  return a + b;
}
