8301313: RISC-V: C2: assert(false) failed: bad AD file due to missing match rule

[DingliZhang]

Please review this backport to riscv-port-jdk11u. Backport of JDK-8301313.
Due to the line numbers and the lack of C2_MacroAssembler in jdk11, it is not possible to apply the original patch directly.

This PR will solve the following problem:
We noticed that slowdebug builds failed on openEuler build system due to bad AD files after upgrading to version 11.0.24-ga.
The issue can be reproduced on LPi4A using the riscv-port branch with the following command:

bash configure \
--with-boot-jdk=$HOME/jdk-bin/openjdk-11/jdk \
--disable-warnings-as-errors \
--with-debug-level=slowdebug \
--with-native-debug-symbols=internal
make images

https://cr.openjdk.org/~dzhang/riscv-port-jdk11u/8301313/hs_err_pid395981.log

Testing:

• Native slowdebug build on LPi4A
• Tier1 passed w/o new failure on LPi4A (release)
