  [X86] Fix register parsing in .seh_* in Intel syntax

Previously, the parser checked for a '%' prefix to indicate a register.
In Intel syntax mode, LLVM does not print a '%' prefix on registers, so
LLVM could not parse its own assembly output. Instead, require that
register numbers be integer literals, or at least start with an integer
literal, which is consistent with .cfi_* directive register parsing.
