Evict a lighter single interference before attempting to split a live range.
Registers are not allocated strictly in spill weight order when live range

There are a couple of problems with this.
1. The encoding for the literal and immediate constant are different.

2. t2LDRi12 is now narrowed to tLDRpci before constant island pass is run.

Implement support for custom target specific asm parsing of operands.
Motivation: Improve the parsing of not usual (different from registers or

This commit implements only the generic support. The ARM specific modifications

A table like the one below is autogenerated for every instruction
containing a 'ParserMethod' in its AsmOperandClass

A matcher function very similar (but lot more naive) to
MatchInstructionImpl scans the table. After the mnemonic match, the
features are checked and if the "to be parsed" operand index is
present in the mask, there's a real match. Then, a switch like the one
below dispatch the parsing to the custom method provided in
'ParseMethod':

a) Making it a per call site bonus for functions that we can move from

b) Reduces the bonus from 500 to 100 per call site.
