[PATCH] D31054: [globalisel][tablegen] Fix patterns involving multiple ComplexPatterns.

[Daniel Sanders via Phabricator via llvm-commits]

Temporaries are now allocated to operands instead of predicates and this
allocation is used to correctly pair up the rendered operands with the
matched operands.

Previously, ComplexPatterns were allocated temporaries independently in the
Src Pattern and Dst Pattern, leading to mismatches. Additionally, the Dst
Pattern failed to account for the allocated index and therefore always used
temporary 0, 1, ... when it should have used base+0, base+1, ...

Thanks to Aditya Nandakumar for noticing the bug.
