Switch implementation
Implemented switch/case for glsl in OpenGL ES 3.0.
For simplicity, it is implemented as a loop without a condition,
so break statements work properly like so:
begin switch
if(...) // 1st case
...
else if(...) // other cases
...
else // default case
...
end switch // Anchor point for break statements
All related dEQP tests pass, except 7 tests where vertex shaders
contain a switch or a loop within another switch. These 7 failures
have only about 5% of bad pixel and seem to be related to an issue
with int(floor(...)), since the equivalent tests inside the fragment
shader pass.
KNOWN ISSUE: If a switch is within a loop and one of the cases
contains a "continue" statement, this will not be
handled correctly at the moment. There are no dEQP
tests for this at the moment, AFAIK.

And from section 6.1.5:
"IsSampler will return TRUE if sampler is the name of a
sampler object previously returned from a call to
GenSamplers and FALSE otherwise".
Also, glIsSampler can use Context::isSampler(), which uses
ResourceManager::isSampler(), which should only look whether a
name has been reserved, not whether the object is allocated.
Note: Even though the spec mentions (about Sampler objects):
"they acquire state only when they are first used as a parameter
to BindSampler, SamplerParameter*, GetSamplerParameter*, or
IsSampler", it shouldn't hurt to not allocate the object when
calling IsSampler, since a subsequent call to any other Sampler
object related function should allocate it.

Fix error on invalid type/format combination.
GL_INVALID_ENUM is for enum values that are never valid for the function.
GL_INVALID_OPERATION is expected for enum combinations that are not valid.

Fix local variable hides function parameter for GLSL ES 1.0
GLSL ES 1.0 specifies that "a function body has a scope nested inside
the function’s definition". For GLSL ES 3.0, they form a single scope.
Both specs use the compound_statement_no_new_scope rule. This change
respects that while supporting both behaviors. It does not impact legacy
content since it makes things more permissive.

Added floating point formats to validateColorBufferFormat,
which is used by glCopyTexImage2D, since it was a missing
part of the previously added floating point extensions.
From the extension spec:

Uniform block register allocation
Uniform blocks members, when unnamed blocks are used, are
used in glsl only with the member's name, without any
reference to the block itself. When this happens, we still
need the whole block to be allocated as one contiguous
structure in the registers. To do that, whenever a member
of an unnamed block is first used, the whole block is
allocated. Also, whenever any member of an unnamed block
attempts to allocate a register, it first verifies if the
parent block has already been allocated. So this means that
both allocation and lookup must be done through the parent
block when dealing with unnamed block members.
