Fix in loading mach files from memory when using DynamicLoaderMacOSXDYLD.
Removed the uuid mismatch warning that could be spit out and any time during debugging and removed the test case that was looking for that. Currently the "add-dsym" or "target symbols add" command will report an error when the UUID's don't match.
Be more careful when checking and resolving section + offset addresses to make sure none of the base addresses are invalid.

the SCEV vector size in LoopStrengthReduce. It is observed that
the BaseRegs vector size is 4 in most cases,
and elements are frequently copied when it is initialized as
SmallVector<const SCEV *, 2> BaseRegs.
Our benchmark results show that the compilation time performance
improved by ~0.5%.

This change introduces a 'kind' attribute for the <Para> tag, that captures the
kind of the parent block command.
For example:
\todo Meow.
used to be just <Para>Meow.</Para>, but now it is
<Para kind="todo">Meow.</Para>

This allows us to keep from chaining LazyCompoundVals in cases like this:
CGRect r = CGRectMake(0, 0, 640, 480);
CGRect r2 = r;
CGRect r3 = r2;
Previously we only made this optimization if the struct did not begin with
an aggregate member, to make sure that we weren't picking up an LCV for
the first field of the struct. But since LazyCompoundVals are typed, we can
make that inference directly by comparing types.
This is a pure optimization; the test changes are to guard against possible
future regressions.

1) allows the use of RIP-relative addressing in 32-bit LEA instructions under
x86-64 (ILP32 and LP64)
2) separates the size of address registers in 64-bit LEA instructions from
control by ILP32/LP64.

r173593 made us a little too eager to associate all code at the end of a
function with the user-written 'return' line. This caused problems with
breakpoints as they'd be set in exception handling code preceeding the
actual non-exception return handling code, leading to the breakpoint never
being hit in non-exceptional execution.
This change restores the pre-r173593 exception handling line information where
the cleanup code is associated with the '}' not the return line.

Prior to the patch, Clang does not properly promote types when a complex
integer operand is combined with an integer via a binary operator, or when
one is assigned to the other in either order. This patch detects when
promotion is needed (and permissible) and generates the necessary code.
The test assmes no target has the same size operands for "char" and
"long long," and that no target performs arithmetic on char operands without
extending them to a larger format first. If there are any targets for
which this is not the case, they should be XFAILed.

Prepare it for vectors of pointers and handle simple cases. We don't handle
complicated cases because accumulateConstantOffset bails on pointer vectors.
Fixes selfhost on i386.
