Clang will only put DEBUG_PRINT fmt strings into rodata if they
are "static const char[]", we were missing the static. So instead
clang generates code to construct the fmt string on the stack which
is wasteful of instructions and stack space.
Before:
```
; DEBUG_PRINT("beam: no PerCPURecord found");
10: 18 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 r1 = 0x0 ll
12: 61 11 00 00 00 00 00 00 w1 = *(u32 *)(r1 + 0x0)
; DEBUG_PRINT("beam: no PerCPURecord found");
13: 15 01 9d 03 00 00 00 00 if r1 == 0x0 goto +0x39d <LBB0_107>
14: b7 01 00 00 75 6e 64 00 r1 = 0x646e75
; DEBUG_PRINT("beam: no PerCPURecord found");
15: 63 1a 78 ff 00 00 00 00 *(u32 *)(r10 - 0x88) = w1
16: 18 01 00 00 65 63 6f 72 00 00 00 00 64 20 66 6f r1 = 0x6f662064726f6365 ll
18: 7b 1a 70 ff 00 00 00 00 *(u64 *)(r10 - 0x90) = r1
19: 18 01 00 00 20 50 65 72 00 00 00 00 43 50 55 52 r1 = 0x5255504372655020 ll
21: 7b 1a 68 ff 00 00 00 00 *(u64 *)(r10 - 0x98) = r1
22: 18 01 00 00 62 65 61 6d 00 00 00 00 3a 20 6e 6f r1 = 0x6f6e203a6d616562 ll
24: 7b 1a 60 ff 00 00 00 00 *(u64 *)(r10 - 0xa0) = r1
25: bf a1 00 00 00 00 00 00 r1 = r10
26: 07 01 00 00 60 ff ff ff r1 += -0xa0
27: b7 02 00 00 1c 00 00 00 r2 = 0x1c
28: 85 00 00 00 06 00 00 00 call 0x6
29: 05 00 8d 03 00 00 00 00 goto +0x38d <LBB0_107>
```
After:
```
; DEBUG_PRINT("beam: no PerCPURecord found");
10: 18 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 r1 = 0x0 ll
12: 61 11 00 00 00 00 00 00 w1 = *(u32 *)(r1 + 0x0)
; DEBUG_PRINT("beam: no PerCPURecord found");
13: 15 01 11 02 00 00 00 00 if r1 == 0x0 goto +0x211 <LBB0_100>
14: 18 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 r1 = 0x0 ll
16: b7 02 00 00 1c 00 00 00 r2 = 0x1c
17: 85 00 00 00 06 00 00 00 call 0x6
18: 05 00 0c 02 00 00 00 00 goto +0x20c <LBB0_100>
