Ted Kremenek fc7052d4a2 Add lightweight shim "clang::StatSysCallCache" that caches 'stat' system calls ... for use by FileManager. FileManager now takes a StatSysCallCache* in its constructor (which defaults to NULL). This will be used for evaluating whether or not caching 'stat' system calls in PTH is a performance win. This shim adds no observable performance impact in the case where the 'StatSysCallCache*' is null. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64345 91177308-0d34-0410-b5e6-96231b3b80d8		2009-02-12 00:39:05 +00:00
