If an initial value is given for a bitfield that does not fit in the bitfield, the value should be truncated. Constant folding for expressions did not account for this truncation in the case of union member functions, despite a warning being emitted. In some contexts, evaluation of expressions was not enabled unless C++11, ROPI or RWPI was enabled.

[test] Add {{.*}} to make tests immune to dso_local/dso_preemptable/(none) differences

[test] Add {{.*}} to make tests immune to dso_local/dso_preemptable/(none) differences
For a definition (of most linkage types), dso_local is set for ELF -fno-pic/-fpie and COFF, but not for Mach-O. This nuance causes unneeded binary format differences.
This patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} ` if there is an explicit linkage.
* Clang will set dso_local for Mach-O, which is currently implied by TargetMachine.cpp. This will make COFF/Mach-O and executable ELF similar. * Eventually I hope we can make dso_local the textual LLVM IR default (write explicit "dso_preemptable" when applicable) and -fpic ELF will be similar to everything else. This patch helps move toward that goal.

[Clang][CodeGen] Fixing mismatch between memory layout and const expressions for oversized bitfields
Summary: The construction of constants for structs/unions was conflicting the expected memory layout for over-sized bit-fields. When building the necessary bits for those fields, clang was ignoring the size information computed for the struct/union memory layout and using the original data from the AST's FieldDecl information. This caused an issue in big-endian targets, where the field's contant was incorrectly misplaced due to endian calculations.
This patch aims to separate the constant value from the necessary padding bits, using the proper size information for each one of them. With this, the layout of constants for over-sized bit-fields matches the ABI requirements.

Complete Rewrite of CGRecordLayoutBuilder
CGRecordLayoutBuilder was aging, complex, multi-pass, and shows signs of existing before ASTRecordLayoutBuilder. It redundantly performed many layout operations that are now performed by ASTRecordLayoutBuilder and asserted that the results were the same. With the addition of support for the MS-ABI, such as placement of vbptrs, vtordisps, different bitfield layout and a variety of other features, CGRecordLayoutBuilder was growing unwieldy in its redundancy.
This patch re-architects CGRecordLayoutBuilder to not perform any redundant layout but rather, as directly as possible, lower an ASTRecordLayout to an llvm::type. The new architecture is significantly smaller and simpler than the CGRecordLayoutBuilder and contains fewer ABI-specific code paths. It's also one pass.
The architecture of the new system is described in the comments. For the most part, the new system simply takes all of the fields and bases from an ASTRecordLayout, sorts them, inserts padding and dumps a record. Bitfields, unions and primary virtual bases make this process a bit more complicated. See the inline comments.
In addition, this patch updates a few lit tests due to the fact that the new system computes more accurate llvm types than CGRecordLayoutBuilder. Each change is commented individually in the review.
