[lld] Bug with Assert in linker scripts

[lquinn2015]

This test https://github.com/llvm/llvm-project/blob/main/lld/test/ELF/linkerscript/assert.s

A semicolon after an Assert statement causes some type of bad state in LLVM lld this is problematic

The error statement is totally misleading

I believe fixing it is as simple as adding a peak consume in the parsing logic of assert statements. credit @pitust I will try and make a fix tomorrow
