VisualStudio project files updated.  #include <algorithm> added to make VisualStudio happy.  Also had to undefine setjmp because of #include <csetjmp> turning setjmp into _setjmp in VisualStudio.

that intrinsics always get the right attributes.
So remove no-longer needed code, and while there use

else that is invoked, they were getting changed to invokes,
which is badness.

2. Do not use # of basic blocks as part of the cost computation since it doesn't really figure into function size.
3. More aggressively inline function with vector code.

not marked nounwind, or for all functions when -enable-eh
is set, provided the target supports Dwarf EH.

llvm-gcc generates nounwind in the right places; other FEs
will need to do so also.  Given such a FE, -enable-eh should
no longer be needed.

Increasing the inline limit from (overly conservative) 200 to 300. Given each BB costs 20 and each instruction costs 5, 200 means a 4 BB function + 24 instructions (actually less because caller's size also contributes to it).

Furthermore, double the limit when more than 10% of the callee instructions are vector instructions. Multimedia kernels tend to love inlining.
