Remove invalid test. This test requires that dead basic blocks be kept
...
around. That's not how we do things. Besides, the commit message tells us that
it is covered by the GCC test suite.

r127497 | zwarich | 2011-03-11 13:51:56 -0800 (Fri, 11 Mar 2011) | 3 lines
Fix the GCC test suite issue exposed by r127477, which was caused by stack
protector insertion not working correctly with unreachable code. Since that
revision was rolled out, this test doesn't actual fail before this fix.

Fixed a problem in the JIT memory allocator where
...
allocations of executable memory would not be padded
to account for the size of the allocation header.
This resulted in undersized allocations, meaning that
when the allocation was written to later the next
allocation's header would be corrupted.

[analyzer] Correctly devirtualize virtual method calls in constructors.

This is the other half of C++11 [class.cdtor]p4 (the destructor side
was added in r161915). This also fixes an issue with post-call checks
where the 'this' value was already being cleaned out of the state, thus
being omitted from a reconstructed CXXConstructorCall.

[analyzer] Only adjust the type of 'this' when we devirtualize a method call.
...
With reinterpret_cast, we can get completely unrelated types in a region
hierarchy together; this was resulting in CXXBaseObjectRegions being layered
directly on an (untyped) SymbolicRegion, whose symbol was from a completely
different type hierarchy. This was what was causing the internal buildbot to
fail.
Reverts r161911, which merely masked the problem.

Add missing Rfalse operand to the predicated pseudo-instructions.
...
When predicating this instruction:
Rd = ADD Rn, Rm
We need an extra operand to represent the value given to Rd when the
predicate is false:
Rd = ADDCC Rfalse, Rn, Rm, pred
The Rd and Rfalse operands are different registers while in SSA form.
Rfalse is tied to Rd to make sure they get the same register during
register allocation.
Previously, Rd and Rn were tied, but that is not required.
Compare to MOVCC:
Rd = MOVCC Rfalse, Rtrue, pred
