lower an expect intrinsic that is a constant expression.

a225da9719 Don't remove a landing pad if the invoke requires a table entry. 
An invoke may require a table entry. For instance, when the function it calls
is expected to throw.

there are any null bytes in the string upfront so we can simplify the comparison

f5194657f8 Don't emit the extra checksum into the .gcda file if the user hasn't asked for 
it. Fortunately, versions of gcov that predate the extra checksum also ignore
any extra data, so this isn't a problem. There will be a matching commit in
compiler-rt.

2346df4d41 Disable statistics on Release builds and move tests that depend on -stats. 
Summary:
Statistics are still available in Release+Asserts (any +Asserts builds),
and stats can also be turned on with LLVM_ENABLE_STATS.

Move some of the FastISel stats that were moved under DEBUG()
back out of DEBUG(), since stats are disabled across the board now.

Many tests depend on grepping "-stats" output.  Move those into
a orig_dir/Stats/. so that they can be marked as unsupported
when building without statistics.

e0efb3660f Assert to bounds check MDNode::getOperand. 
The getOperandPtr utility already bounds checks, but allows one-off-the-end.
This assert should catch the cases that could previously have been dereferencing
these one-off-the-end pointer. Happily, no cases of this came up with this
change.

many-versions old debug info metadata format)
