All check-tsan tests fail on aarch64-*-linux because HeapMemEnd() > ShadowBeg()
for the following code path:
```
#if defined(__aarch64__) && !HAS_48_BIT_ADDRESS_SPACE
ProtectRange(HeapMemEnd(), ShadowBeg());
```
Restore the behavior before D86377 for aarch64-*-linux.
This reverts commit bde2e56071.
This patch produces a compile failure on linux amd64 environments, when
running:
ninja GotsanRuntimeCheck
I get various build errors:
../rtl/tsan_platform.h:608: error: use of undeclared identifier 'Mapping'
return MappingImpl<Mapping, Type>();
Here's a buildbot with the same failure during stage "check-tsan in gcc
build", there are other unrelated failures in there.

Disable huge pages in the TSan shadow regions when no_huge_pages_for_shadow == true (default).
