This is not necessarily the first or dominating use of the EH values. The IR
breaks if it's not. So replace the specific value in the instruction with the
new value.

Polly adds, after it is loaded into opt or clang, its passes to the default set
of -O3 passes. This means optimizing a program with clang and Polly becomes as
simple as executing.

clang -Xclang -load -Xclang lib/LLVMPolly.so -O3 program.c

The same should work for dragonegg powered gfortran, g++, ... or any other tool
that uses the PassManagerBuilder.

Warning: Even though using Polly became with this commit extremly easy, Polly
         is still Pre-Alpha Quality. This means in most cases it will rather
         destroy the world than doing anything positive. ;-)

Refactor and fix checking for initialization of flexible array members.  The old version had the checks scattered across the code, missed some checks, and had a couple nasty bugs in existing checks.

Fixes PR10648 and another similar accepts-invalid bug.

The invoke could be at the end of the entry block. If it's the only one, then we
won't process all of the landingpad instructions correctly. This code is
currently ugly, but should be made much nicer once the new EH switch is thrown.

It should go before AsmPrinter MC pseudo expansion since it's based on
MachineInstr, not MCInst. Otherwise any frame related pseudo instructions
may be missed.

Renamed format "signed decimal" to be "decimal". "unsigned decimal" remains unchanged:
 - the name "signed decimal" was interfering with symbol %S (use summary) in summary strings.
   because of the way summary strings are implemented, this did not really lead to a bug, but
   simply to performing more steps than necessary to display a summary. this is fixed.
Documentation improvements (more on synthetic children, some information on filters). This is still a WIP.

expression parser.  You can use a persistent
type like this:

(lldb) expr struct $foo { int a; int b; };
(lldb) struct $foo i; i.a = 2; i.b = 3; i
($foo) $0 = {
  (int) a = 2
  (int) b = 3
}

typedefs work similarly.

This patch affects the following files:

test/expression_command/persistent_types/*
  A test case for persistent types,
  in particular structs and typedefs.

ClangForward.h
  Added TypeDecl, needed to declare some
  functions in ASTResultSynthesizer.h

ClangPersistentVariables.[h,cpp]
  Added a list of persistent types to the
  persistent variable store.

ASTResultSynthesizer.[h,cpp]
  Made the AST result synthesizer iterate
  across TypeDecls in the expression, and
  record any persistent types found.  Also
  made a minor documentation fix.

ClangUserExpression.[h,cpp]
  Extended the user expression class to
  keep the state needed to report the
  persistent variable store for the target
  to the AST result synthesizers. 

  Also introduced a new error code for
  expressions that executed normally but
  did not return a result.

CommandObjectExpression.cpp
  Improved output for expressions (like 
  declarations of new persistent types) that
  don't return a result.  This is no longer
  treated as an error.

to increased calls to SourceManager::getFileID. (rdar://9992664)

Use a slightly different approach that is more efficient both in terms of speed
(no extra getFileID calls) and in SLocEntries reduction.

Comparing pre-r138129 and this patch we get:

For compiling SemaExpr.cpp reduction of SLocEntries by 26%.
For the boost enum library:
  -SLocEntries -34% (note that this was -5% for r138129)
  -Memory consumption -50%
  -PCH size -31%

Reduced SLocEntries also benefit the hot function SourceManager::getFileID,
evident by the reduced "FileID scans".
