[asan] Use proper shadow offset for loongarch64 in instrumentation passes
Instrumentation passes now use the proper shadow offset. There will be many
asan test failures without this patch. For example:
```
$ ./lib/asan/tests/LOONGARCH64LinuxConfig/Asan-loongarch64-calls-Test
AddressSanitizer:DEADLYSIGNAL
=================================================================
==651209==ERROR: AddressSanitizer: SEGV on unknown address 0x1ffffe2dfa9b (pc 0x5555585e151c bp 0x7ffffb9ec070 sp 0x7ffffb9ebfd0 T0)
==651209==The signal is caused by a UNKNOWN memory access.
```
