callGraph.push_front -> emplace_front to fix UBSAN

UBSAN rightly complains on `push_front` here:

    glslang/MachineIndependent/localintermediate.h:100:8: runtime error: load of value 160, which is not a valid value for type 'bool'

What happens here:

1. TCall's bool fields are not initialized on construction.
2. `push_front` move the `TCall` passed into it.
3. The move constructor copies unitialized bool, which may have an
   out-of-range value.

What this fix does:

Calls `emplace_back` to ensure no copy/move constructor is called.

Ben Clayton [Mon, 19 Oct 2020 21:21:12 +0000 (22:21 +0100)]
Fix uninitialized use of TIntermediate::resource (#2424)

TIntermediate was constructed without initializing any of the `resources` fields,
and `TProgram::linkStage()` was not calling `TIntermediate::setLimits()`
after constructing new `TIntermediate`s for non-first stages.

Fields of `resources` were then read in `TIntermediate::finalCheck()`
triggering undefined behavior.

This CL makes three changes:
(1) `TIntermediate::setLimits()` is now called for non-first stages by
    copying the `firstIntermediate`'s limits. This ensures that the
    `resources` fields is initialized, fixing the bug.
(2) `TIntermediate::resources` is now wrapped in a `MustBeAssigned<>`
    helper struct, asserting in non-release builds that this field is
    always initialized before reading.
(3) `TIntermediate::resources` is now zero-initialized, so that if
    the `TIntermediate::resources` field is not set in a release build
    (and so the `assert()` will be disabled) behavior is still
    deterministic.
