[lldb] Remove some calls to GetASTContext
GetASTContext is really expensive to call as it makes use of the global
mapping from ASTContext to ClangASTContext. This replaces all calls
where we already have the ClangASTContext around and don't need to call
GetASTContext again.

[compiler-rt] Disable QSORT interception on watchOS and tvOS.
Building the sanitizers for watchOS currently fails with error: thread-local storage
is not supported for the current target
   static THREADLOCAL SIZE_T qsort_size;
I've also speculatively disabled QSORT interception for tvOS to unblock
failing builds. I'll ask someone with more sanitizer knowledge to check
after the holidays.
