coala-antlr Enhancement

Particularly i will start by adding the grammars which will be asm8080,asm8086 which is intel based processors.For that language definitions for the same will be added in coala.Now the bears for them will be added as of now there are no bears which works for the microprocessors or microcontrollers.Similarly a grammar will be updated on upstream for PIC microcontrollers where a language definition will also be included in coala for the same.Henceforth the bears for the microcontroller and microprocessors will be supported by this project.Basically bears will be used to style the opcode like capitalization of special functions registers etc. which are used for ADC, sensors interfacing.
Apart from this i am planning to make a tree rewriting based on the above grammars generated trees it could be done using the generated template, if it is possible
"without having that functionality on the upstream antlr".

Start by reviewing the proposed asm8080, asm8086, and PIC grammars, along with the corresponding coala language definitions. Determine the scope for opcode-styling bears and whether tree rewriting is feasible with generated ANTLR trees; the work is done only when these supported grammars, definitions, bears, and rewriting behavior are specified and implemented.
