produce better diagnostics, and be more correct in ObjC cases (fixing
rdar://6803963).

An example is that we now diagnose:

int test1(int x) {
  goto L;
  int a[x];
  int b[x];
  L:
  return sizeof a;
}

with:

scope-check.c:15:3: error: illegal goto into protected scope
  goto L;
  ^
scope-check.c:17:7: note: scope created by variable length array
  int b[x];
      ^
scope-check.c:16:7: note: scope created by variable length array
  int a[x];
      ^

instead of just saying "invalid jump".  An ObjC example is:

void test1() {
  goto L;
  @try {
L: ;
  } @finally {
  }
}

t.m:6:3: error: illegal goto into protected scope
  goto L;
  ^
t.m:7:3: note: scope created by @try block
  @try {
  ^

There are a whole ton of fixme's for stuff to do, but I believe that this
is a monotonic improvement over what we had.

Add a new LiveInterval::overlaps(). It checks if the live interval overlaps a range specified by [Start, End).

into the wrong section (they shared the same lookup table).

add some comments, change type from void* -> Stmt*, use
smallvector instead of vector.

AST context's __builtin_va_list type will be set when the PCH file is
loaded. This fixes the crash when CodeGen'ing a va_arg expression
pulled in from a PCH file.

Highlights: PP::isNextPPTokenLParen() no longer eats the ( 
when present.  We now simplify slightly the logic parsing
macro arguments.  We now handle PR3937 and other related cases
correctly.

for the optimization it's testing to kick in (although
it improves the code, getting rid of all spills).
I don't understand the optimization well enough to
rescue the test, so XFAILing.

my earlier patch to this code only fixed half of it.

llvm-svn: 69408

"Hello, World!", this takes us from deserializing 6469
statements/expressions down to deserializing 1
statement/expression. It only translated into a 1% improvement on the
Carbon-prefixed 403.gcc, but (a) it's the right thing to do, and (b)
we expect this to matter more once we lazily deserialize identifiers.

lazy PCH deserialization. Propagate that argument wherever it needs to
be. No functionality change, except that I've tightened up a few PCH
tests in preparation.

from a PCH file. It turns out that "Hello, World!" is bringing in 19%
of all of the statements in Carbon.h, so we need to be lazy.
