[jdk18] RFR: 8277621: ARM32: multiple fastdebug failures with "bad AD file" after JDK-8276162

[Hao Sun]

JDK-8276162 introduced an optimization that creates the following two
kinds of IR shapes:

1. `CMoveI (Bool (CmpUL ...) ...)`: conditionally moving two ints based
on the comparison result of two unsigned longs.

2. `CMoveP (Bool (CmpUL ...) ...)`: conditionally moving two pointers
based on the comparison result of two unsigned longs.

But the corresponding match rules are missing for arm32. JDK-8277324 and
JDK-8277753 complemented the missing rules for x86-32. We do the same
thing to arm32 in this patch.

For IR shape 1, the missing rules in arm32 are in form of
"cmovIL_AA_BB_U", where AA can be reg/imm16/immMov(i.e. three variants
of moving immediate/register), and BB can be LTGE/EQNE/LEGT(i.e. three
condition code registers for unsigned long comparisons).

For IR shape 2, the missing rules are in form of "cmovPL_CC_BB_U", where
CC can be reg/imm, and BB has the same meaning with IR shape 1.

Minor updates:
1. "cmpOpUL/comOpUL_commute" should be used for "cmovLL_AA_BB_U" rules.
2. Rename "cmovIL_imm_BB" rules to "cmovIL_imm16_BB".
3. Add "cmovIL_immMov_BB" rules.
4. Style issue: remove the extra space in the predicate statement for
cmov* rules.

Test:
We ran tier 1~3 tests on arm32 platform. With this patch, "bad AD file"
errors are gone without introducing test regression.
