For PR411:
...
This patch is an incremental step towards supporting a flat symbol table.
It de-overloads the intrinsic functions by providing type-specific intrinsics
and arranging for automatically upgrading from the old overloaded name to
the new non-overloaded name. Specifically:
llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64
llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64
llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64
llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64
llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64
New code should not use the overloaded intrinsic names. Warnings will be
emitted if they are used.

Use the ClonedCodeInfo object to avoid scans of the inlined code when

it doesn't contain any calls. This is a fairly common case for C++ code,
so it will probably speed up the inliner marginally in these cases.

Fix a bug I noticed by inspection: if the first instruction in the inlined
...
function was not an alloca, we wouldn't check the entry block for any allocas,
leading to increased stack space in some cases. In practice, allocas are almost
always at the top of the block, so this was never noticed.
