Dan Gohman accaca5604 Fix (at least) quadratic worst-case complexity in DominanceFrontier::splitBlock: 
don't visit all blocks in the function, and don't iterate over the split blocks'
predecessor lists for each block visited.

Also, remove the special-case test for the entry block. Splitting the entry
block isn't common enough to make this worthwhile.

This fixes a major compile-time bottleneck which is exposed now that
LoopSimplify isn't being redundantly run both before and after
DominanceFrontier.

Sebastian Redl ae8cbb7220 Make sure that implicit qualification and derived-to-base conversions of xvalues preserve xvalue-ness. Unfortunately I have no idea how to test this property; there doesn't seem to be a syntactical construct that triggers such a conversion and still allows the distinction between prvalues and xvalues to be made.

Douglas Gregor 67ca40c419 Eliminate the "minimal" and printing parser actions, which only ever 
worked for C anyway. Also kills the -cc1 options -parse-noop and
-parse-print-callbacks.

Rafael Espindola 235457ca7f Clone and restore the module being reduced in 
ReduceMiscompilingFunctions::TestFuncs. This makes the test functional
(i.e., no side effects).

Before we would end up using dead functions if a pass decided to remove them
(inline for example) and we would also keep broken functions and conclude that
that a single function was enough to reproduce the bug.

Nick Lewycky a3f7dcd069 Don't pass -export-dynamic to the linker on Cygwin and MinGW. These platforms 
accept the flag and do nothing but warn about it, cleverly bypassing our
configure-based detection system. Patch by Takumi Nakamura!

Douglas Gregor f2430ba223 Start removing the use of smart pointers from the Parse/Sema 
interaction, by effectively defaulting to
DISABLE_SMART_POINTERS. We're embracing the model where all AST nodes
are ASTContext-allocated and live as long as the ASTContext lives.
