Jordy Rose 7a53498f20 [analyzer] Reapply 138382 and 138388 (reverted in 138419 and 138420). The issue seems to have been with the uninitialized variable fixed in 138424; a fix for another Heisencrasher coming soon.

Anna Zaks 0897a23517 [analyzer] MacOSKeychainAPIChecker: Add reasoning about functions which MIGHT deallocate the memory region allocated with SecKeychain APIs. Specifically, when the buffer is passed to CFStringCreateWithBytesNoCopy along with a custom deallocator, which might potentially correctly release the memory.

Bill Wendling f4ee0c0db2 Add the sentinal "no handle" value to the ResumeInst. 
A value of -1 at a call site tells the personality function that this call isn't
handled by the current function. Since the ResumeInsts are converted to calls to
_Unwind_SjLj_Resume, add a (volatile) store of -1 to its 'call site'.

Ted Kremenek bd91371381 Start reworking -Wunreachable-code. The original analysis had serious flaws with how it 
handled SCC's of dead code, or simply having false negatives by overly suppressing warnings.

Bill Wendling 2d4f0bea57 Don't replace *all* uses with the new stuff. 
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.

Tobias Grosser 792509b0db Register Polly passes automatically 
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. ;-)

Eli Friedman 3fa64df543 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.

Bill Wendling 01a325a40e Look at the end of the entry block for an invoke. 
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.

Jim Grosbach 51b554247d Move ARM frame-unwinding EHABI handling a touch earlier. 
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.
