the functional change here is changing ConvertType -> ConvertTypeForMem
so that we handle i1 fields properly as memory.

Optimize PCH encoding for switch-case statements slightly, by making
the switch-case numbering local to a particular statement.

llvm-svn: 69355

Add a few commented lines to the test case that point out things that don't work yet.

llvm-svn: 69354

Use a safer iterator interface and get rid of std C++ library misuse.
This fixes a --enable-expensive-checks problem.

llvm-svn: 69353

Regenerate configure.

llvm-svn: 69352

Add a --enable-profiling option to configure to build Debug+Profile and
Opt+Profile tools.  Now we can profile any kind of flavor we build.

 - This is a simple but effective way to allow developers to build a

register is available and when it's profitable.

e.g.
     xorq  %r12<kill>, %r13
     addq  %rax, -184(%rbp)
     addq  %r13, -184(%rbp)
==>
     xorq  %r12<kill>, %r13
     movq  -184(%rbp), %r12
     addq  %rax, %r12
     addq  %r13, %r12
     movq  %r12, -184(%rbp)

Two more instructions, but fewer memory accesses. It can also open up
opportunities for more optimizations.

If a class has a non-trivial constructor that doesn't take any arguments, we will now make an implicit CXXTemporaryObjectExpr. So 

struct S {
  S();
};

void f() {
 S s;
}

's' here will implicitly be declared as.

S s = S();
