xtensa: constantsynth: Add new 3-insns synthesis pattern
This patch adds a new 3-instructions constant synthesis pattern:
- A value that can fit into a signed 12-bit after a number of either bitwise
left or right rotations:
=> "MOVI(.N) Ax, simm12" + "SSAI (1 ... 11) or (21 ... 31)"
+ "SRC Ax, Ax, Ax"
gcc/ChangeLog:
* config/xtensa/xtensa.cc (xtensa_constantsynth):
Add new pattern for the abovementioned case.
gcc/testsuite/ChangeLog:
* gcc.target/xtensa/constsynth_3insns.c (test_4):
Add new test function.
