cortexm: add __isr_vector symbol
This doesn't change the firmware, but it does make the disassembly of
the ELF files. Before:
Disassembly of section .text:
00000000 <(machine.UART).Write-0x100>:
0: 20001000 .word 0x20001000
4: 000009db .word 0x000009db
8: 00000f05 .word 0x00000f05
c: 00000f0b .word 0x00000f0b
10: 00000f05 .word 0x00000f05
After:
Disassembly of section .text:
00000000 <__isr_vector>:
0: 20001000 .word 0x20001000
4: 000009db .word 0x000009db
8: 00000f05 .word 0x00000f05
c: 00000f0b .word 0x00000f0b
10: 00000f05 .word 0x00000f05
The difference is that the disassembler will now use a proper symbol name
instead of using the closest by symbol (in this case, (machine.UART).Write).
This makes the disassembly easier to read.
