[EfficiencySanitizer] Using '$' instead of '#' for struct counter name

[slthakur]

Summary

For MIPS '#' is the start of comment line. Therefore we get assembler errors if # is used in the structure names.

[zhaoqin]

We use '#' to make the name less likely to conflict with user defined variables.
Can we use some other char that cannot be used by program variables e.g., '+' or '-' instead of '_'.
Also, you also need update names in test/Instrumentation/EfficiencySanitizer/ and runtime tests.

Addressed review comments.
