analysis. Currently captures all variables by reference.

This broke e.g. compiling a crash report from a glibc system on Darwin. Sadly,
the implementation had to game the lexer a lot as we're not using a real
preprocessor here. It also doesn't handle special cases like arbitrary macros in
__has_include, but since this macro isn't common outside of clang's headers we
can get away with that.
Fixes PR14422.

- There is no reason to have a modules specific flag for disabling
autolinking. Instead, convert the existing flag into -fno-autolink (which
should cover other autolinking code generation paths like #pragmas if and
when we support them).

Show an error message when we have a corrupt mach-o file where the LC_SEGMENT or LC_SEGMENT_64 load command have file offsets or file offsets + sizes that extend beyond the end of the file.

The SPARC v8 and SPARC v8 architectures are very similar, so use a base
class to share most information between them.
Include operating systems with known SPARC v9 ports.
Also fix two issues with the SPARC v8 data layout string: SPARC v8 is a
big endian target with a 64-bit aligned stack.

If a switch instruction has a case for every possible value of its type,
with the same successor, SimplifyCFG would replace it with an icmp ult,
but the computation of the bound overflows in that case, which inverts
the test.

Regions that have multiple entry edges are very common. A simple if condition
yields e.g. such a region:
if
/ \
then else
\ /
for_region
This for_region contains two entry edges 'then' -> 'for_region' and 'else' -> 'for_region'.
Previously we scheduled the RegionSimplify pass to translate such regions into
simple regions. With this patch, we now support them natively when the region is
in -loop-simplify form, which means the entry block should not be a loop header.

a UUID for the shared cache libraries that can be used to confirm
that one process' shared cache is the same as another, or that a
process' in-memory shared cache is a match for a given on-disk
dyld_shared_cache binary file. Use these UUIDs to catch some
uncommon problems when the shared caches are being changed for debug
purposes.

When computing the value of ?: expression, we rely on the last expression in
the previous basic block to be the resulting value of the expression. This is
not the case for binary "?:" operator (GNU extension) in C++. As the last
basic block has the expression for the condition subexpression, which is an
R-value, whereas the true subexpression is the L-value.
Note the operator evaluation just happens to work in C since the true
subexpression is an R-value (like the condition subexpression). CFG is the
same in C and C++ case, but the AST nodes are different, which the LValue to
Rvalue conversion happening after the BinaryConditionalOperator evaluation.
Changed the logic to only use the last expression from the predecessor only
if it matches either true or false subexpression. Note, the logic needed
fortification anyway: L and R were passed but not even used by the function.
Also, change the conjureSymbolVal to correctly compute the type, when the
expression is an LG-value.
