Nirav Dave 9263ae3b5a Fix handling of end-of-line preprocessor comments Attempt 2
Attempt 2: Retryign after Tsan.mman test fix.

Attempt 1: Recommitting after fixing test.

When parsing assembly where the line comment syntax is not hash, the
lexer cannot distinguish between hash's that start a hash line comment
and one that is part of an assembly statement and must be distinguished
during parsing. Previously, this was incompletely handled by not checking
for EndOfStatement at the end of statements and interpreting hash
prefixed statements as comments.

Change EndOfStatement Parsing to check for Hash comments and reintroduce
Hash statement parsing to catch previously handled cases.
