400e59ba21 Remove the NEON N2VSInt instruction class: it's only used in one place and 
since it has no pattern, there's not much point in distinguishing an "N2VS"
class for intrinsics anyway.

ea55421ec2 More cleanup for NEON: 
* Use "S" abbreviation for scalar single FP registers in class and pattern
names, instead of keeping the "D" (for "double") abbreviation and tacking on
an "s" elsewhere in the name.
* Move the scalar single FP register classes and patterns to be more
consistent with other definitions in the file.
* Rename "VNEGf32d" definition to "VNEGfd" for consistency.
* Deleted the N2VDIntsPat pattern; N2VSPat is good enough.

8f3afbc621 Emulate the current isel's "IsChainCompatible" logic for now. 
I'd like to eventually rip it out, but for now producing the
same selections as the old matcher is more important.

a6df2a60e5 prefix captured value names with $ so they look like 
variables.  Use the fancy OpNo variable instead of i,
which has the right index including chains.

6e98127ab8 Initial implementation of PIC16 Cloner pass. 
This pass is supposed to be run on the linked .bc module.
It traveses the module call graph twice. Once starting from the main function
and marking each reached function as "ML". Again, starting from the ISR
and cloning any reachable function that was marked as "ML". After cloning
the function, it remaps all the call sites in IL functions to call the
cloned functions. 

Currently only marking is being done.
