Tighten up regexps some more.

These tests were failing for me because the .* was greedily matching up
to the /libexec/ld-elf.so.1" later on the same line.

Enabling the UTF conversion routines that were previously conditionally ifdef'ed out. This change is required to support enhancements in the LLDB data formatters

Use custom ABIInfo for le32/PNaCl argument codegen

This patch uses a new ABIInfo implementation specific to the le32
target, rather than falling back to DefaultABIInfo. Its behavior is
basically the same, but it also allows the regparm argument attribute.
It also includes basic tests for argument codegen and attributes.

[ms-inline asm] The IR representation of inline assembly enumerates the input
and output expressions much like that in GNU-style inline assembly. Output
expressions are first.  Do this for MS-style inline asms.

[analyzer] Don't attempt to devirtualize calls to base class destructors.

CXXDestructorCall now has a flag for when it is a base destructor call.
Other kinds of destructor calls (locals, fields, temporaries, and 'delete')
all behave as "whole-object" destructors and do not behave differently
from one another (specifically, in these cases we /should/ try to
devirtualize a call to a virtual destructor).

This was causing crashes in both our internal buildbot, the crash still
being tracked in PR13765, and some of the crashes being tracked in PR13763,
due to a assertion failure. (The behavior under -Asserts happened to be
correct anyway.)

Adding this knowledge also allows our DynamicTypePropagation checker to do
a bit less work; the special rules about virtual method calls during a
destructor only require extra handling during base destructors.

Tweak DeadStoresChecker to not warn about dead stores to variables that
are used in EH code.  Right now the CFG doesn't support exceptions well,
so we need this hack to avoid bogus dead store warnings.

[analyzer] Don't crash if we cache out while evaluating an ObjC message.

A bizarre series of coincidences led us to generate a previously-seen
node in the middle of processing an Objective-C message, where we assume
the receiver is non-nil. We were assuming that such an assumption would
never "cache out" like this, and blithely went on using a null ExplodedNode
as the predecessor for the next step in evaluation.

Although the test case committed here is complicated, this could in theory
happen in other ways as well, so the correct fix is just to test if the
non-nil assumption results in an ExplodedNode we've seen before.
