[Mesa-dev] [PATCH] radeon/llvm: Don't use the global context when parsing LLVM IR

[Tom Stellard]

From: Tom Stellard <thomas.stellard at amd.com>

This leads to crashes when multiple threads try to compile compute
shaders in the same time.

Fixes a crash in bfgminer when using more than one thread.
