[PATCH] Simplify the PNaCl/le32 ABI to ignore regparm

[Derek Schuff]

I think it might be better to just throw an error on regparm
attributes (i.e. by setting regParmMax=0 in PNaClTargetInfo) rather
than ignoring them. That way if someone tries to build against glibc
headers (the reason for this code's existence in the first place), it
will fail loudly rather than just silently generating incompatible
code.
