Hello,
This is a cherry pick of 20385cb92cbd4a1934661ab97a162c1e25935836 which didn't
apply cleanly
so needed a very minor edit to for it to apply for GCC 12 and 13.
Regtested and bootstrapped for gcc-13 on aarch64-linux-gnu.
This applies cleanly to gcc-12 but there is a regression for
`c-c++-common/hwasan/large-aligned-1.c`.
The output of execution was
```
==2242916==ERROR: HWAddressSanitizer: tag-mismatch on address 0xfffffffff680 at
pc 0xfffff780e08c
READ of size 4 at 0xfffffffff680 tags: 02/01(00) (ptr/mem) in thread T0
#0 0xfffff780e08c in SigTrap<2>
../../../../src/libsanitizer/hwasan/hwasan_checks.h:28
```
and has changed to
```
==2242927==ERROR: HWAddressSanitizer: tag-mismatch on address 0xfffffffff690 at
pc 0xfffff780e08c
READ of size 4 at 0xfffffffff690 tags: 02/00 (ptr/mem) in thread T0
#0 0xfffff780e08c in SigTrap<2>
../../../../src/libsanitizer/hwasan/hwasan_checks.h:28
```
Note the difference in the tags.
Does anyone with experience of HWAddressSanitizer know what caused this and if
it's an issue?
Kind regards,
Alfie Richards
