[Beignet] [PATCH 6/7] backend: Add ASM file name to GenContext object.

[Manasi Navare]

From: Laura Ekstrand <laura.d.ekstrand at intel.com>

Part of the plumbing that passes the ASM file name from the compiler options
level down to the emitCode level so that the assembly can be written to that
file.
