|  02ef64f012 These functions are defined in compiler-rt in assembly and therefore
don't have stack size information. However, they're often called so
these missing functions often inhibit stack size calculation.
Example, before:
    $ tinygo build -o test.elf -target=cortex-m-qemu -print-stacks ./testdata/float.go
    function                         stack usage (in bytes)
    Reset_Handler                    unknown, __aeabi_memclr does not have stack frame information
    runtime.run$1                    unknown, __aeabi_dcmpgt does not have stack frame information
After:
    $ tinygo build -o test.elf -target=cortex-m-qemu -print-stacks ./testdata/float.go
    function                         stack usage (in bytes)
    Reset_Handler                    260
    runtime.run$1                    224 | ||
