**** Changes in v3 ****
Fix bugs exposed by dpmpyss_rnd_s0 instruction
Set correct size/signedness for constants
Test cases added to tests/tcg/hexagon/misc.c
**** Changes in v2 ****
Fix bug in imm_print identified in clang build
Currently, idef-parser skips all floating point instructions. However,
there are some floating point instructions that can be handled.
The following instructions are now parsed
F2_sfimm_p
F2_sfimm_n
F2_dfimm_p
F2_dfimm_n
F2_dfmpyll
F2_dfmpylh
To make these instructions work, we fix some bugs in parser-helpers.c
gen_rvalue_extend
gen_cast_op
imm_print
lexer properly sets size/signedness of constants
Test cases added to tests/tcg/hexagon/fpstuff.c

We only need to track slot for predicated stores and predicated HVX
instructions.
Add arguments to the probe helper functions to indicate if the slot
is predicated.
Here is a simple example of the differences in the TCG code generated:
IN:
0x00400094: 0xf900c102 { if (P0) R2 = and(R0,R1) }
BEFORE
---- 00400094

mov_i32 new_r2,r2
and_i32 tmp0,p0,$0x1

processed by idef-parser.
