4d6337dfaf Supporting instruction Bit Field Insert 1 
The bfi1 instruction component-wise generates mask with control
from src0 and src1 and stores the results in dst.

c3f1e0a732 Supporting addc instruction 
The addc instruction performs component-wise addition of
src0 and src1 and stores the results in dst;
it also stores the carry into acc.

8ca55688ea Supporting bit field extract and bit field insert 2 
Supporting two new operators, bfe and bfi2
bfe: Component-wise extracts a bit field from src2 using the bit field width from src0 and the bit field offset from src1.
bfi2: component-wise performs the bitfield insert operation on src1 and src2 based on the mask in src0.

a034bcbd04 Support trinary source instruction "multiply add". 
MAD (Multiply ADd) computes dst <- src1*src2 + src0.

Tried best to follow previous variable naming habit.

Also renamed "triinstruction" -> "trinaryinstruction" in grammar parser
for better readability.

aab7cd5cc5 close File yyin before calling yylex_destroy 
This patch makes sure file handler yyin is closed.
yylex_destroy() calls yy_init_globals(), which reset yyin to 0.
Therefore if we do not close yyin before yylex_destroy(), yyin
will not be closed anymore.

27050395d2 Support DP for sampler/render/constant/data cache 
Since Sandybridge, DP supports cache select for read/write. Some write messages such as
OWord Block Write don't support render cache any more on Ivybridge. So introduce a
generic data_port messsage for Sandybridge+.

    data_port(
        cache_type,   /* sampler, render, constant or data(on Ivybridge+) cache */
        message_type, /* read or write type */
        message_control,
        binding_table_index,
        write_commit_or_category, /* write commit on Sandybridge, category on Ivybridge+ */
        header_present)

e97f0bca5f sampler/render/constant cache unit since Sandybridge 
since Sandybrdige, there isn't a single function unit for data port read/write.
Instead sampler/render/constant cache unit is introduced, data port read/write
can be specified in a SEND instruction with different cache unit. To keep compatibility,
currently data port read always uses sampler cache unit however data port write
uses render cache unit
