Also fix some comments.

Change it back again: destructors and constructors need to be run.

This fixes the MC/COFF/basic-coff.ll test case.

getMaxRegionExit returns the exit of the maximal refined region starting
at a specific basic block.

are still on the list.  This might happen if a CallbackVH created some new value
handles for the old value when doing RAUW.  Barf if it occurs, since it is almost
certainly a mistake.

add assembly implementation of modsi3 so compiler does not have to special case a - (a / b) * b optimization

Revert r109428 "Hoist argument type checking into CheckFormatHandler.  This is prep for scanf format"

Got errors about ASTContext being undefined with Visual Studio 2010.

* Improve getNameStr() to return a sensible name, if basic blocks are not named.

subregister operands like this:

%reg1040:sub_32bit<def> = MOV32rm <fi#-2>, 1, %reg0, 0, %reg0, %reg1040<imp-def>; mem:LD4[FixedStack-2](align=8)

Make them return false when subreg operands are present. VirtRegRewriter is
making bad assumptions otherwise.

This fixes PR7713.

The next step is to warn if a block labeled unreachable is, in fact, reachable. Somewhat related to PR810.

Add PTHLexer::LexEndOfFile() to emit diagnostics at end-of-file similar to those by Lexer::LexEndOfFile().

PTH generation: Don't save the leading '#' token in a null directive.  This unbreaks using PTH with Boost (<rdar://problem/8227989>).

protectors, to be near the stack protectors on the stack. Accomplish this by
tagging the stack object with a predicate that indicates that it would trigger
this. In the prolog-epilog inserter, assign these objects to the stack after the
stack protector but before the other objects.

Groundwork for C string length tracking. Currently only handles the length of constant string literals, which is not too helpful, and only calls to strlen() are checked.

A good start on ecma regex's.  Maybe even feature complete, not sure yet.  Also an unrelated fix to is_constructible thanks to Daniel Krugler.

that the values they refer to aren't being deleted underneath them.

Make sure these containters get cleared by clear(), which IndVarSimplify
and LSR both use before deleting instructions.

trying to do replaceUsesOfWith on a constant,
which doesn't work.  Turns out we don't need to
do anything for constants.

it returns a list of functions as a SymbolContextList.

Rewrote the clients of SymbolContext to use this
SymbolContextList.

Rewrote some of the providers of the data to SymbolContext
to make them respect preferences as to whether the list
should be cleared first; propagated that change out.

ClangExpressionDeclMap and ClangASTSource use this new
function list to properly generate function definitions -
even for functions that don't have a prototype in the
debug information.

of the usual consistency checks used to determine when a precompiled
header is incompatible with the translation unit it's being loaded
into.

Enable this option when loading a precompiled preamble, because the
preamble loader will be performing all of this checking itself. Enable
the preamble-based test now that it's working.

This option is also useful for debugging Clang's PCH
(<rdar://problem/7532213>).

- Stop reading in (and thus deserializing) every declaration in the TU when creating a dependent PCH.
- Switch the storage of a decl context's lexical declarations to a blob containing the IDs instead of a record. This is the only sane way of supporting update records later on.
