Ayke van Laethem 02ef64f012 stacksize: hardcode some more frame sizes for __aeabi_* functions

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
