findLSB, findMSB, and countBits always return a signed integer
Fixes:
dEQP-GLES31.functional.shaders.builtin_functions.uniform.findLSBMinusOne.*
dEQP-GLES31.functional.shaders.builtin_functions.integer.findmsb.*
dEQP-GLES31.functional.shaders.builtin_functions.integer.bitcount.*
Changes resulting from the discussion on mesa-dev with
Roland Schneidegger:
v2: Set values in infer_(src|dst)_type only
v3: Set values in the common infer_type code path, and only add
the source type for UMSB

This just pulls in a bunch of TGSI changes from upstream
that make adding GLES3.1 features easier.

This is a basic step towards GL4.0 and greater,
add support for the FP64 extension.
This requires ARB_gpu_shader5 on the host, to
implement ldexp using bitfieldInsert.
v2: drop fp64_srcs into local var
fix imul regression due to rebase
