Fix PR6282: the include guard optimization cannot happen if the
...
guard macro is already defined for the first occurrence of the
header. If it is, the body will be skipped and not be properly
analyzed for the include guard optimization.

Work around an annoying, non-standard optimization in the glibc
...
headers, where malloc (and many other libc functions) are declared
with empty throw specifications, e.g.,
extern void *malloc (__SIZE_TYPE__ __size) throw () __attribute__
((__malloc__)) ;
The C++ standard doesn't seem to allow this, and redeclaring malloc as
the standard permits (as follows) resulted in Clang (rightfully!)
complaining about mis-matched exception specifications.
void *malloc(size_t size);
We work around this by silently propagating an empty throw
specification "throw()" from a function with C linkage declared in a
system header to a redeclaration that has no throw specifier.
Ick.

Add a new pass on machine instructions to optimize away PHI cycles that
...
reduce down to a single value. InstCombine already does this transformation
but DAG legalization may introduce new opportunities. This has turned out to
be important for ARM where 64-bit values are split up during type legalization:
InstCombine is not able to remove the PHI cycles on the 64-bit values but
the separate 32-bit values can be optimized. I measured the compile time
impact of this (running llc on 176.gcc) and it was not significant.
