Fix invalid conversion from "const char *" to "char *" for linux systems. strchr() on darwin returns "char *" so we weren't seeing this issue on MacOSX.

Fixed an error where the thread index was being returned as zero in "uint32_t SBBreakpoint::GetThreadIndex() const" even when it isn't specified. It should be UINT32_MAX to indicate there is no thread index set for the breakpoint (the breakpoint isn't thread specific). Also fixed the ThreadSpec.cpp to use UINT32_MAX instead of -1. Fixed the logging Printf statement in "uint32_t SBBreakpoint::GetThreadIndex() const" to not print the address of the "index" function from <string.h>!

While LLVM's main design is that analysis code shouldn't
go out of its way to understand code which hasn't been
InstCombined, analysis utility routines like this can
find themselves being called in the middle of transform
passes when instcombine hasn't had a chance to run.

parameter packs within a statement, type, etc. Use this visitor to
provide improved diagnostics for the presence of unexpanded parameter
packs in a full expression, base type, declaration type, etc., by
highlighting the unexpanded parameter packs and providing their names,
e.g.,

test/CXX/temp/temp.decls/temp.variadic/p5.cpp:28:85: error: declaration type
      contains unexpanded parameter packs 'VeryInnerTypes',
      'OuterTypes', ...

 * mergeIn now uses constant folding for constants that are provably not-equal.
 * sink some sanity checks from the get*() methods into the mark*() methods, to ensure that we never have a constant/notconstant ConstantInt
 * some textual cleanups, whitespace changes, removing "else" after return, that sort of thing.

Diagnostic pragmas are broken because we don't keep track of the diagnostic state changes and we only check the current/latest state.
Problems manifest if a diagnostic is emitted for a source line that has different diagnostic state than the current state; this can affect
a lot of places, like C++ inline methods, template instantiations, the lexer, etc.

Fix the issue by having the Diagnostic object keep track of the source location of the pragmas so that it is able to know what is the diagnostic state at any given source location.

Fixes rdar://8365684.

Bypass loops have the current live range live through, but contain no uses or
defs. Splitting around a bypass loop can free registers for other uses inside
the loop by spilling the split range.

This method returns the set of loops with uses that are candidates for
splitting.

Move the work-in-progress implementation of variadic templates to its own file in Sema. No functionality change.

This is still a WIP.  It's already good enough to expose a few bugs, though.

Some quad-register intrinsics with lane operands only take a double-register
operand for the vector containing the lane.  The valid range of lane numbers
is then half as big as you would expect from the quad-register type.
Note: This currently has no effect because those intrinsics are now handled
entirely in the header file using __builtin_shufflevector, which does its own
range checking, but I want to use this for generating tests.

BuildExpressionFromIntegralTemplateArgument can produce malformed
IntegerLiterals with an EnumType if the template parameter type
is an EnumType.  This breaks the AST printer which expects all
IntegerLiterals to have a plain integer type.  Instead, give the
IntegerLiteral the enum's promotion type and wrap in an implicit cast
to the EnumType.
