Support configuration-specific known failures in asm_tests

This allows Known_Failures files to contain either:
- Partial paths (existing): Test_X87_F64/SomeTest.asm (affects all configs)
- Full paths (new): jit_1/Test_64Bit_X87_F64/SomeTest.asm (specific config)

For example: Mark only the jit_1 (-n 1) configuration as failing:
jit_1/Test_64Bit_X87_F64/Memcopy_int_F64.asm
