tweaks to make the "don't configure if already
configured" logic work.

With this, sqlite3 now passes.

This avoids using a dangling pointer.

Reset NumSortedEntries after restoring Cache to avoid extraneous sorts.
This fixes the reduced sqlite3 testcase, but apparently not the whole app.

Only check if coalescing is worthwhile when the result is targeting a more restrictive register class.

This also helps performance.  Pre-alloc-splitting now seems to be an overall win on SPEC.

   be useless?

 - Requires providing some option parameters to over-ride rendering in
   order to match gcc. There may be a cleaner way to do this (probably
   by introducing a new option type for long JoinedOrSeparate forms).

 - Unlike groups (which gather distinct but related options), aliases
   are for options like '--all-warnings' which are effectively treated
   like some other option ('-Wall') both in the driver logic and when
   passing to tools.

For now, return UnknownVal() in RegionStore::getElementsSize() for AnonTypedRegions.  It wasn't really doing the right thing and was crashing on rdar-6442306-1.m.  This fix causes all path-sensitive test cases to pass with RegionStore.

load is always aligned.

I verified that the bswap doesn't occur in the assembly code on x86.

llvm-svn: 62815

Add RegionStore support for the implicit object region that 'self' references.  This causes tests 'ObjCProperties.m' and 'refcnt_naming.m' to now pass with RegionStore.

we've processed a multi-designator designation. We're matching GCC and
EDG's behavior on all examples I've found thus far.

*Huge* thanks to Eli Friedman for pointing out my fundamental
misunderstanding of "current object" in the C99 spec.
