[NVPTX] Integrate ptxas to LIT tests

ptxas is a proprietary compiler from Nvidia that can compile PTX to
machine code (SASS). It has a lot of diagnostics to catch errors
in PTX, which can be used to verify PTX output from llc.

Set -DPXTAS_EXECUTABLE=/path/to/ptxas CMake option to enable it.
If this option is not set, then ptxas is substituted to true which
effectively disables all ptxas RUN lines.

LLVM_PTXAS_EXECUTABLE environment variable takes precedence over
the CMake option, and allows to override ptxas executable that is used for LIT
without complete re-configuration.

[NVPTX] Fix for NVPTX module asm regression

Currently module asm ends up emitted twice and at the wrong place in the PTX.
This patch moves module asm generation into emitStartOfAsmFile() which puts at
the correct location in the generated PTX.

[NVPTX] Add support for module-scope inline asm

Since we were explicitly not calling AsmPrinter::doInitialization,
any module-scope inline asm was not being printed.
