This object controls when the warnings are executed, allowing the client code
in Sema to selectively disable warnings as needed.
Centralizing the logic for analysis-based warnings allows us to optimize
when and how they are run.
Along the way, remove the redundant logic for the 'check fall-through' warning
for blocks; now the same logic is used for both blocks and functions.

load/stores with address register writeback, and use "odd" suffix to distinguish
instructions to access odd numbered registers (instead of "a" and "b").
No functional changes.

writeback, and refactor the existing double-spaced VLD2 instructions.
These are only for the disassembler since codegen doesn't use them, at
least for now.

We were inserting a value into a std::vector<> while iterating over
it, which could cause the underlying memory to get deallocated
and reallocated. While not the best solution, use an llvm::ImmutableList
for now as it is safely supports insertions during iteration.

load/store optimizer would incorrectly think that registers D26 and D28
were consecutive and would generate a VLDM instruction to load them.
The assembler was not convinced.

expression computation in the wrong bit-width, and end up generating a totally
bogus array reference (_g0+8589934546).
- This showed up on Prolangs/cdecl.

so that the SCEVExpander doesn't retain a dangling pointer as its
insert position. The dangling pointer in this case wasn't ever used
to insert new instructions, but it was causing trouble with
SCEVExpander's code for automatically advancing its insert position
past debug intrinsics.
This fixes use-after-free errors that valgrind noticed in
test/Transforms/IndVarSimplify/2007-06-06-DeleteDanglesPtr.ll and
test/Transforms/IndVarSimplify/exit_value_tests.ll.

preprocessed entities by grouping preprocessed entities by file
ID. This drastically improves performance of repeated
clang_getCursor() calls local tests, although it is a bit ugly.

shadowing it in the GlobalDeclMap. Eliminates the string-uniquing
requirement for mangled names, which should help C++ codegen times a little.
Forces us to do string lookups instead of pointer lookups, which might hurt
codegen times a little across the board. We'll see how it plays out.
Removing the string-uniquing requirement implicitly fixes any bugs like
PR6635 which arose from the fact that we had multiple uniquing tables for
different kinds of identifiers.
